[PATCH 1/1] aoe: ignore vendor extension AoE responses

[Ed Cashin]

The Welland ME-747K-SI AoE target generates unsolicited AoE
responses that are marked as vendor extensions.  Instead of
ignoring these packets, the aoe driver was generating kernel
messages for each unrecognized response received.  This patch
corrects the behavior.

I will place this patch in the new aoe quilt tree for
linux-next when this patch has passed LKML review.
