Small foam piece broke off of motherboard

[Snafoo]

Hi everyone.

I am in the process of disassembling my mid-2011 A1286 MacBook Pro so that I can replace the keyboard.

As I was taking the motherboard out, I accidentally ripped a small, gray foam piece off of the bottom of the ethernet port.

Can anyone tell me what this is? And how I go about reattaching it? Thanks!

Here's a picture of the piece:

Here's a picture of where it was:

Looks like one of the various gaskets that you will find inside laptops. Its purpose is to provide some control of RF energy, and perhaps to help to control mechanical movement of the ports in the reassembled MBPro. If you know where it was located, you can simply stick it back in place. If the port side is no longer sticky, you can use a small piece of double-sided tape to re-attach it.
