(In reply to Kristof Provost from comment #10)

My apologies Kristof, I'm unable to add any value here.

I'm using product ID=0x772b (ASIX Electronics Corporation, an AX88772B 10/100)
while Dmitry is using 0x7e2b (we're using the same vendor 0x0b95), and both
devices are regarded as AX88772B.  Unfortunately I was responding to the
interface ue0 as being the problem. Regardless, we aren't comparing apples to
oranges - as I am getting successful connections albeit with bad cksums; which
I continue to get after disabling pf (via pfctl -d)

References:
Note from /usr/src/sys/dev/usb/net/if_axereg.h
 * This driver does not enable partial checksum feature which will
 * compute 16bit checksum from 14th byte to the end of the frame.  If
 * this feature is enabled, computed checksum value is embedded into
 * RX header which in turn means it uses different RX header format.
