ASIX requires a login account to get the data sheet so it's not
publicly available to open source developers.
AFAIK the difference between AX88772A and AX88772B is IPv4/IPv6
checksum offloading support of AX88772B. The introduction of
checksum offloading means they might have changed its RX header
format which in turn makes current RX handler to not work. The
other difference would be more advanced power saving used in
AX8877B but it wouldn't be much difference to axe(4) driver once
PHY is correctly woken in initialization phase.
Could you show me your diff and verbose boot output to know PHY
model and EEPROM data?
