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.
