No it does not, tried to go from 1500 to 9000 and then to 1300 and 1000.
No change at all. Only if i start TX from the LAN interface, then RX is
working as expected. As soon as TX stops, RX comes to crawl. I have
attached iper3 log to show this. The times when speed is in MBits is
when i started
Does changing MTU help?

Hello Kai-Heng,
i have tested provided kernel and it still suffers from slow speed. Also
noticed, that if i run iperf3 multiple times, it works in one-two passes
and then it slows down to crawl. Then again on the next pass it works as
expected. Please see attached outputs.

I have found workaround to get LAN working. On Ubuntu kernel
5.11.0-18-generic if i boot up system and log in - LAN is not working
correctly - CRC errors etc. If laptop is put into hibernate (save to
swap partition), then turned on and system state restored from
hibernation, LAN adapter is working
