net: adjust skb_gso_segment() for calling in rx path
skb_gso_segment() is almost always called in tx path, except for openvswitch. It calls this function when it receives the packet and tries to queue it to user-space. In this special case, the ->ip_summed check inside skb_gso_segment() is no longer true, as ->ip_summed value has different meanings on rx path. This patch adjusts skb_gso_segment() so that we can at least avoid such warnings on checksum. Cc: Jesse Gross <jesse@nicira.com> Cc: David S.
