| |
2.6.32-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.
