[PATCH 3.2 17/87] asix: silence log message from oversize packet

[Ben Hutchings]

3.2.77-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: stephen hemminger <stephen@xxxxxxxxxxxxxxxxxx>

commit b70183db83552cf63cac51406aaf76a2cf5fca73 upstream.

Since it is possible for an external system to send oversize packets
at anytime, it is best for driver not to print a message and spam
the log (potential external DoS).
