| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Ed Cashin <ecashin@coraid.com>
commit b6d6c5175809934e04a606d9193ef04924a7a7d9 upstream.
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.
