A previous patch (net: asix: fix operation without eeprom) added a two-byte shift to the packet buffer when receiving a packet on the AX88772B.
This shift was not included when the driver was updated to work with DriverModel. Testing on a Marvell DB-88F6820-ACM showed that the adapter was not functioning correctly (EHCI timeouts).
This patch brings the two-byte shift to the DriverModel implementation of ops->recv (asix_eth_recv).
Testing on the same board, we were able to TFTP a file over and confirm that the crc32 was correct.
