Subject[54/71] gro: reset skb_iif on reuse
2.6.33-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: Andy Gospodarek <andy@greyhouse.net>

commit 6d152e23ad1a7a5b40fef1f42e017d66e6115159 upstream.

Like Herbert's change from a few days ago:

66c46d741e2e60f0e8b625b80edb0ab820c46d7a gro: Reset dev pointer on reuse

this may not be necessary at this point, but we should still clean up
the skb->skb_iif. If not we may end up with an invalid valid for
skb->skb_iif when the skb is reused and the check is done in
__netif_receive_skb.
