aoe: ignore vendor extension AoE responses
Ed Cashin [Wed, 18 Feb 2009 22:48:13 +0000 (14:48 -0800)]
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.
