+Subject: [PATCH] r8169: fix rx checksum offload
+
+While porting GRO to r8169, I found this driver has a bug in its rx
+path.
+
+All skbs given to network stack had their ip_summed set to
+CHECKSUM_NONE, while hardware said they had correct TCP/UDP checksums.
+
+The reason is driver sets skb->ip_summed on the original skb before the
+copy eventually done by copybreak. The fresh skb gets the ip_summed =
+CHECKSUM_NONE value, forcing network stack to recompute checksum, and
+preventing my GRO patch to work.
+
+Fix is to make the ip_summed setting after skb copy.
+
+Note : rx_copybreak current value is 16383, so all frames are copied...
