SubjectRe: [PATCH] netpoll: make arp replies through netpoll use mac address of sender

Applied, and I'll push this to -stable, thanks Neil.

But please submit networking patches next time to
netdev@vger.kernel.org, most of the networking developers did not see
this patch because you sent it to the user help list (linux-net)
instead of the developer list (netdev).

Thanks again.
