netpoll_pass_skb_to_rx_hook.patch

From: Jason Wessel <jason.wessel@windriver.com>
CC: mpm@selenic.com
Subject: [PATCH] Pass skb via NET_POLL rx routine

This patch is a chane to the NET POLL api so that the MAC address or
IP frame information can be parsed by the driver that wishes to use
it.  Speficially for kgdboe, it is used to automatically collect the
MAC address of the GDB host.
