From e95feb47e0f0841557e88c4270ae4c332f194290 Mon Sep 17 00:00:00 2001 From: Andy Gospodarek Date: Wed, 2 Feb 2011 14:53:25 -0800 Subject: [PATCH] gro: reset skb_iif on reuse 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. Signed-off-by: Andy Gospodarek Signed-off-by: David S.
