From 70386d40e19eeff8696f2593755e78f6f7fa9e6d Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 20 Mar 2013 09:33:19 -0700 Subject: [PATCH] chelsio: add headroom in RX path Drivers should reserve some headroom in skb used in receive path, to avoid future head reallocation. One possible way to do that is to use dev_alloc_skb() instead of alloc_skb(), so that NET_SKB_PAD bytes are reserved. Signed-off-by: Eric Dumazet Signed-off-by: David S.
