Date: Thu, 8 Nov 2012 19:23:16 -0500 From: Ed Cashin <ecashin@...aid.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org, ecashin@...aid.com Subject: [PATCH 4/8] aoe: err device: include MAC addresses for unexpected responses The /dev/etherd/err character device provides low-level information about normal but sometimes interesting AoE command retransmits and "unexpected responses", i.e., responses for packets that have already been retransmitted. This change adds MAC addresses to the messages about unexpected responses, so that when they occur, it's more easy to determine the network paths to which they belong.
