This is wrong approach. (we can not process old board similar as new)

Looking in commit 639e298f432fb0 (e1000e: Fix packet loss on Tiger Lake and later) I would suggest to replace the mac->type as follow:
"if (mac->type >= e1000_pch_tgp)" with "if (mac->type >= e1000_pch_cnp)" (more correct) - try it on your side.

I checked this variant first of all - the behavior is correct, network packets are not lost. Can I prepare a new patch or will this change be made by you?
