Subject: [PATCH 0/2] Disable forwarding of LRO skbs

Large Receive Offload (LRO) destroys packet headers that should be
preserved when forwarding.  Currently it also triggers a BUG() or WARN()
in skb_gso_segment().  We should disable it wherever forwarding is
enabled, and discard LRO skbs with a warning if it is turned back on.

Ben.
