Hi,

Did anybody else notice that the ATTO FastFrame NQ41 and NQ42 are rebranded Mellanox ConnectX-3 CX353A and CX354A cards? ATTO provides the bin firmware files on their website, all you likely need to do to get a generic Mellanox CX3 card to work is cross flash its firmware with ATTO's bin file. This is easy with mst / flint using Mellanox's Firmware Tools package.

1. Download Mellanox Firmware Tools: https://www.mellanox.com/products/adapter-software/firmware-tools
2. Download ATTO NQ41/NQ42 Firmware: https://www.atto.com/downloads/174/driver/29300356
3. Run the following:

mst start;

# NQ41 - Single Port Card
flint --allow_psid_change -d /dev/mst/mt4099_pci_cr0 -i flsbundle_nq41_2017_09_05.bin burn;

# NQ42 - Dual Port Card
flint --allow_psid_change -d /dev/mst/mt4099_pci_cr0 -i flsbundle_nq42_2017_09_05.bin burn;

4. Put device in a Mac and install ATTO's FastFrame macOS drivers.

I haven't tested this yet but it should work just fine, I cross flash Dell branded Mellanox cards all the time back to stock Mellanox firmware. I don't have a QSFP cable that is long enough to reach my Mac, but as soon as I do I'll flash one of mine and report back. CX3 cards can be picked up on eBay for about $40, the part numbers you should be looking for are CX353A-FCBT or CX354A-FCBT, these support up to 56 GbE. The CX353A-QCBT or CX354A-QCBT may also work, these support up to 40 GbE. At this time, the ATTO driver appears to only work with ConnectX-3 Pro CX313A and CX314A cards; the supported device id type (i.e. chipset model) is 4103. MCX313A-BCBT and MCX314A-BCBT are presumed to not be compatible because their device id is reportedly 4099.

It appears the ATTO cards are device id 4103, which are ConnectX-3 Pro devices.

    Current FW version on flash:  2.42.5000

    Note: The new FW version is the same as the current FW version on flash.

 Do you want to continue ? (y/n) [n] : y


    You are about to replace current PSID on flash - "DEL1100001019" with a different PSID - "ATT1060111023".
    Note: It is highly recommended not to change the PSID.

 Do you want to continue ? (y/n) [n] : y

I sorta got it working with the regular ConnectX-3 MCX353A-FCBT, all I did was generate a new firmware image using the [HCA] section from the INI file above and also changed the PSID. My device is a single port, so everything below relates to the single port ATTO FastFrame NQ41, steps for the dual port could be slightly different.

These are the commands / steps I did:

# Backup current firmware on the Mellanox card and the INI file:
flint -d /dev/mst/mt4099_pci_cr0 ri DEL1100001019.bin;
flint -d /dev/mst/mt4099_pci_cr0 dc > DEL1100001019.ini;

# Create a new INI file using the INI file from the previous step as the foundation:
cp -a DEL1100001019.ini ATT1060111023.ini;

# Swap out the [HCA] section and change PSID under the [ADAPTER] section with the following:
vim ATT1060111023.ini

[ADAPTER]
PSID = ATT1090111023

[HCA]
hca_header_subsystem_vendor_id = 0x117c
hca_header_device_id = 0x1007
hca_header_subsystem_id = 0x0091
hca_header_class_code = 0x020000
eth_xfi_en = true
mdio_en_port1 = 0
pcie_tx_polarity = 0x00
dpdp_en = false
cmpl_timeout_default_value_en = 1

# Download Mellanox's firmware development kit, you need the fw-ConnectX3-rel.mlx file.
# I can't find "fw-ConnectX3-rel.mlx" version 2.42.5000, if you have a copy send it my way please.
wget http://content.mellanox.com/firmware/ConnectX3-rel-2_40_5030.tgz;
tar -axf ConnectX3-rel-2_40_5030.tgz;

# Download Mellanox's Firmware Tools package and install, and also install the extra mft-oem package, mft-oem contains the tools necessary to create new firmware images.
wget http://content.mellanox.com/MFT/mft-4.14.0-105-x86_64-deb.tgz;
tar -axf mft-4.14.0-105-x86_64-deb.tgz;
cd mft-4.14.0-105-x86_64-deb;
./install.sh;
dpkg -I ./DEBS/mft-oem_4.14.0-105_amd64.deb;

# Create a new firmware image using the fw-ConnectX3-rel.mlx and ATT1060111023.ini files, output file is fw-ConnectX3-rel-2_40_5030-ATT1060111023.bin:
mlxburn -wrimage fw-ConnectX3-rel-2_40_5030-ATT1060111023.bin -fw fw-ConnectX3-rel.mlx -conf ATT1060111023.ini;

# Start mst services if not already started:
mst start;

# Flash new firmware image onto the Mellanox card:
flint --allow_psid_change -d /dev/mst/mt4099_pci_cr0 -i fw-ConnectX3-rel-2_40_5030-ATT1060111023.bin burn;

# Reboot for the new firmware image to take effect:
reboot;

After rebooting the Linux host, the Subsystem now identifies as ATTO, vfio-pci is attached because I'm running macOS Mojave inside of a KVM VM on a Ubuntu 20.04 system, so I'm doing PCIe device passthrough of the Mellanox card into the VM... this could potentially be the cause for why it's not working right... I still need to get a 10 meter QSFP cable to reach all the way to my Mac Pro 2012.

Code:

From within the macOS Mojave VM I get the following:

I found a Mellanox QSFP to SFP+ adapter so I was able to try this in my Mac Pro 2012, unfortunately it did not work... but it feels very close to working... I'm willing to bet if I had a genuine ConnectX-3 Pro (I only have regular CX3 right now, not the Pro version) it would work. In the screenshot below it appears the card lost it's MAC addresses. I checked with flint and it's still there, but on closer investigation it appears the ATTO driver can't access the NVRAM region of the regular non-pro CX3 card. I'm going to stop here until I can get my hands on a real CX3 Pro.

Hi. This is extremely interesting. How sure are you that it'll work with the ConnectX-3 Pro? I'm about to get one on Ebay to test that with our 2013 MacPro (in external TB PCI box) and our server.
Do you think those specs should be good? Model No: CX314A, P/N: MCX314A-BCCT, Pro version, CONNECTX-3Pro EN 40 Gigabit Ethernet Adapter PCI-E 2-Port MELLANOX.

Yes I would be willing to bet that it'll work, and the MCX314A-BCCT card has the correct device id of 4103. The most important thing to ensure is that the device id matches the one in the ATTO card, and this one does. Best of luck, please post your results... unfortunately I haven't had the spare cash to buy one of these cards to test yet due to the whole covid-19 pandemic. Your worst case is the driver simply won't work, and if that happens then you can flash it back to the stock firmware and just return it to the seller on eBay.

This is really cool! Shame all my Mellanox Connect-X 3 cards are either the CX354A or CX353A. Would be curious if there was a way to get those to work!

There is probably a way to hack the ATTO driver to use stock Mellanox cards but I don’t know how to do that off the top of my head and I don’t have any slack time to research it right now.

Hi. I just ordered the MCX314A-BCCT and should have it by 1st of June at the latest. I'll report here or ask questions.

Hi nbritton

I got my Connect X3-pro and flashed the firmware in Linux. Put it in my Mac Pro.
But unfortunately it looks like I'm at the exact same point like you were:

I did manage to flash the firmware again on the mac but it doesn't change anything. Looks like the same issue with NVRAM. Do you have any ideas on how to proceed?

Edit: I got a bit further. I could restore the NVRAM to default settings with atinicnvr and now the NVRAM not found message disappeared. Still the same in the ATTO config tool. Maybe we would need a proper ATTO Nvram file to copy onto the card?

Hi
I didn't manage to get it to work. In the end I got a Chelsio 40gbe pci card, which are sold as cheap as the Mellanox on Ebay and works flawlessly with an official driver in OS X
Hi Simon, I'm going down this rabbit hole now. I am having trouble with the Chelsio T62100-LP-CR. I have a connection to my TrueNAS and it works great, but then it always drops the shares. I just ordered a used T5 40G to see how it goes.

Can you tell me which version of macOS you're running and any special tricks you may have done to get 'er running smoothly?

Has anyone been successful? Otherwise, what Chelsio cards do people recommend and have they been stable? I keep getting weird drops during large transfers on a Solarflare card and wouldn't mind better performance. Drivers are 10.9 vintage, so not surprised I'm running into issues.

Do the Chelsio cards work with QSFP to SFP+ adapters? Generic QSFP or branded?

What about device support in Big Sur? The other elephant in the room is obviously the Apple Silicon situation...

I've been using the Chelsio T580-LP-CR for a few days and I can say it definitely did not drop shares in a Thunderbolt enclosure. I just installed into my Mac Pro 7,1 and so far it's running fine. It's only been 10 minutes though, so I'll report back if it drops shares. The 100G card kept dropping shares in the Mac Pro, but I was having better luck in the TB enclosure.

I'm not sure about the SFP+, but I would just buy two so you can run 40G. Chelsio uses generic/Cisco.
 
:) Dear Gentlemans,
did you read the log files after flashing ?
The cross flashed cards are obviously missing their MAC addresses !
Without the MAC the Mellanox cards are known to disable the driver in Windows, Linux and FreeBSD - macOS won’t make an exception.
Who will be the first to flash the MAC back ? (flint and mst can do that).
Don’t worry - you can’t brick the Mellanox cards - there is a jumper labeled FNP - firmware not present.
If you connect these two pins the card will be visible to the os but the firmware (if corrupted) will not be loaded (livefish-mode).
Also you can access and flash the firmware via the onboard I2C header (SDA/SCX).
The NVRAM is stored in an 24C32 i2c device - to my knowledge it’s not used by macOS.

Anyone notice ATTO FastFrame NQ41 / NQ42 are rebranded ConnectX-3 CX353A / CX354A cards?
The FW .bin is on ATTO's website & may only require "Cross-Flashing" a generic CX3's FW with ATTO's.
Which should be doable using Mellanox's mstflint + the Mellanox Firmware Tool package.

I paraphrased your first entry ... which was also referenced in another MR discussion re TB + SFP28

Are there no adapters which are natively supported with MacOS ..?

Exactly:

It's all fine n dandy to be committed to legacy products (Chelsio is even provided drivers for Catalina).
BUT ... once you want to use an M1 or newer ... or Monterey ... the plot thickens. :(

On the other hand -- there is actually a project somewhere to try to create a unified kernel of FreeBSD and MacOS.
Though ... sounds like a poor idea to hold one's breath waiting for such a lofty endeavor to come to fruition. lol.

Good read here ... I will note: The pictures of ATTO's FF N352 and N312 (the latter being quite tenuous as nothing but a 2019 Mac Pro presently has the bandwidth to take advantage of it -- as TB3 is limited to 22Gb/s DATA within MacOS and only in Linux can one tune the reserved bandwidth in a way that's beyond my ability) ... but still, the N351 / N352 look to me..? Like a ConnectX-4. Specifically, the Mellanox MCX416A ... as in, every single chip appears to be identical per pictures I've found of each.

I'm not saying I'm correct; but it just looks that way to me.

Anyway, I have an older ThunderLink (TB1 or 2 to SFP+) ... which I'm tempted to open up and see if it'll recognize any other adapters if there's a PCIe slot in it. If anything good comes of it I'll report back.

Otherwise -- good luck.

I'd be really interested to see what effect this has. Looking at the man page, it looks like it might be as easy as appending --mac XX:XX:XX:XX:XX:XX (where XX:XX:XX:XX:XX:XX is an arbitrary MAC) after the burn command to flash the card. Especially worth trying if the MAC is also blank in Linux.

I might track one of these down myself. An easily-available 40 gigabit ethernet card backed by drivers from a company as responsive as ATTO would be really great, especially as DriverKit looms.

So I’ve got a cx3pro crossflashed to the ATTO firmware but yeah, same issue here. The card works fine in the Linux host where I flashed it - MAC addresses show up, interface comes up and is usable, etc but putting it in a mac results in the dreaded 00’d MAC address. I haven’t poked around but I’d guess it’s something silly like the NVRAM being at a different i2c address on the card since the atto tools specifically say they can’t talk to the nvram (based on other posts above, haven’t personally tried this yet).

It’s definitely not “missing” MAC addresses because the card boots up fine and interacts with the local network as expected after the crossflash on a Linux host. I suspect something silly like a changed i2c address for the NVRAM on the ATTO card since this is super simple to change in a mass-produced product and makes it “just” incompatible enough for people who simply cross-flash.

Sadly whatever is different can't be explained by just the .ini files. A quick diff between my card flashed to stock cx3pro firmware versus the atto firmware yields nothing too interesting:

root@thefloyd-dt:~/atto# diff atto.ini stock.ini

I think we're going to need a dump of the nvram from someone with the ATTO card. Anyone here able to do that?

Hi Simonji,
I have the original atto card. May I help you with something ?
hi churek:

A copy of the NVRam contents would be ideal. On my machine with the current drivers it looks like the command is (from a terminal window):

cd /Applications/ATTO/FastFrame2

sudo ./atnetnvr2 -s ~/Documents/attonvram.backup

(alternatively, sudo ./atnetnvr2 -s /full/path/to/attonvram.backup if you don't want it in your personal Documents folder)

You should end up with a file called attonvram.backup in your 'Documents' folder (modern OSX may prompt you to allow things to write to 'Documents' when you execute this, feel free to save anywhere you're comfortable, this just seemed easy). It doesn't appear from the command line help that you need to specify a device specifically:

thefloyd@Patricks-MacBook-Air-2 FastFrame2 % ./atnetnvr2

Usage:

atnetnvr2 <options> [command]

Options:

-a {length} Set the TX ring buffer length.
-b {length} Set the RX ring buffer length.
{length} is the number of ring buffer entries.
Valid values are 64-8192. 0 indicates driver default.
-c {channel} Selects a specific controller channel for the operation,
starts at 1. For dual port adapters, you must also
specify the port number with -c {channel}:{port},
eg. -c 1:1 for the first port and -c 1:2 for the second.
-d {feature} Disable an NVRAM feature.
-e {feature} Enable an NVRAM feature.
{feature} values:
adapcoal Adaptive interrupt coalescing.
checksum Hardware checksum offloads.
dcb Enable DCB.
rsc Receive Side Coalescing.
tso Enable Transmit Segmentation Offload.
-h Display extended help.
-i {usecs} Set the interrupt coalescing. {usecs} is a number of
microseconds from 0 to 1000.
-l List the controllers in the system.
-m {bytes} Threshold size for inline transmits.
Valid values are 0-104, with 0 disabling inlining.
-p Print the contents of the NVRAM when other operations
are complete.
-q {length} TX queue length.
Valid values are 8-8192. 0 indicates driver default.
-r {filename} Restore the NVRAM from a file.
-s {filename} Save the NVRAM to a file.
-t Restore the NVRAM to default settings.
-v Print tool version information.
-z {length} Set the Transmit Segmentation Offload length.
{length} is the number of TSO bytes.
Valid values are 1500-65536. 0 indicates driver default.


No options found.


I'm going to try and poke at this more at some point today myself, but without a 'genuine' NVRam we might not get far.
