From 8981f01001c616f58f1623ecadfab8b1ed758da7 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 11 Jun 2009 20:55:17 -0700 Subject: [PATCH] virtio_net: Fix IP alignment on non-mergeable RX path We need to enforce the IP alignment on the non-mergeable RX path just like the other RX path. Not doing so results in misaligned IP headers. Signed-off-by: Herbert Xu Signed-off-by: Rusty Russell Signed-off-by: David S.
