From: Marek Vasut <marek.vasut@xxxxxxxxx>
The AX88772B uses only 11 bits of the header for the actual size. The other bits
are used for something else. This causes dmesg full of messages:
asix_rx_fixup() Bad Header Length
This patch trims the check to only 11 bits. I believe on older chips, the
remaining 5 top bits are unused.
