Commit147271209a
("net: asix: fix operation without eeprom") added a special handling for ASIX 88772B that enable another type of header. This break the driver in DM mode as the extra handling needed in the receive path is missing. However this new header mode is not required and only seems to increase the code complexity, so this patch revert this part of commit147271209a
. This also reverts commit41d1258ace
("net: asix: Fix AX88772B when used with DriverModel") of late. Fixes:147271209a
