    Subject[54/74] gro: reset skb_iif on reuse
    2.6.32-longterm review patch.  If anyone has any objections, please let us know.


    From: Andy Gospodarek <>

    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
