(Get the code!)
I am having a similar issue with my Thinkpad L15 Gen2 (Intel), running Ubuntu 21.04 with Kernel 5.11.0-25-generic: After a suspend/resume cycle, the LAN interface only receives at very low speed (less than 1 MBit/sec reported by iperf). So far only rebooting brought back the full speed (approx. 950 MBits/sec.).
It seems that using the MEI fix from #77 also fixes the problem in this scenario - after applying the fix the network speed was back to normal immediately, and I tried several suspend/resume cycles with no decrease in network speed anymore.
