-Subject: NET: skip GRO for otherhost packets
-
-For network drivers using napi_gro_receive, packets are run through GRO,
-even when the destination MAC address does not match, and they're supposed
-to be delivered to another host behind a different bridge port.
-
-This can be very expensive, because for drivers without TSO or scatter-
-gather, this can only be undone by copying the skb and checksumming it
-again.
-
-Fix this by leaving skbs with PACKET_OTHERHOST untouched.
