No one answered for 15inch MBP 2017, this is what I get in system info:
Card Type: AirPort Extreme (0x14E4, 0x173)
Firmware Version: Broadcom BCM43xx 1.0 (7.77.37.31.1a9)

Not that helpful, but chip is probably Broadcom BCM43xx, but I do not know what the xx stands for. Unluckily, there is huge number of such chips. May be someone is smarter...

I am pretty sure the xx is a placeholder saying the driver works with all BCM43 series 1.0 chipsets. There are well over a billion of these in use in phones alone, so it is quite popular.
