When RX checksum offloading is active, AX88772B will prepend a

Browse Source 
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.
