+Subject: [PATCH] 8139cp: fix missing napi_gro_flush.
+
+The driver uses __napi_complete and napi_gro_receive. Without it, the
+driver hits the BUG_ON(n->gro_list) assertion hard in __napi_complete.

+Date: Fri, 30 Dec 2011 23:44:42 +0000
+Subject: [PATCH] 8139cp: properly config rx mode after resuming
+
+Rx mode should be reset after resming, so unconditionally updating rx
+mode rather than conditionally updating based on the value we
+remembered, otherwise unexpected value may be used by the nic after
+resuming.
+
+btw. I find and test this when debugging guest hibernation in qemu, as
+I did not have a 8139cp card in hand, this patch is untested in a
+physical 8139cp card, plase review it carefully.
