pch_gbe: fix ip_summed checksum reporting on rx
Veaceslav Falico [Mon, 25 Mar 2013 22:26:21 +0000 (22:26 +0000)]
[ Upstream commit 76a0e68129d7d24eb995a6871ab47081bbfa0acc ]

skb->ip_summed should be CHECKSUM_UNNECESSARY when the driver reports that
checksums were correct and CHECKSUM_NONE in any other case. They're
currently placed vice versa, which breaks the forwarding scenario. Fix it
by placing them as described above.
