Subject: When RX checksum offloading is active, AX88772B will prepend a
checksum header. The header contains a received frame length but the defined
length for AX88772B is different with other ASIX controllers. When the RX
checksum is off, AX88772B controller does not prepend a checksum header so
driver has to use normal header length mask. This change should fix RX errors
when RX checksum offloading is off.
