+Subject: NET: skip GRO for foreign MAC addresses
+
+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.
+
+To be able to track foreign MAC addresses in an inexpensive way, create
+a mask of changed bits in MAC addresses of upper devices. This allows
+handling VLANs and bridge devices with different addresses (as long as
+they are not too different).
