well, i recompiled 5.15.10 with that change and network is still not
working. then i disabled NetworkManager and rebooted. after boot i
issued following commands:
# ethtool -d eth0
# ip link set dev eth0 up
# ethtool -d eth0
for 5.15.5 (working kernel), 5.15.8 (unmodified, not working kernel),
5.15.10 (modified as above, not working kernel).
obviously, in these register dumps there are 3 different mac addresses
(8 bytes at offset 0x0104) ... but the rest could provide a clue (for
someone who can make sense of those values).
