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.

delay_eeprom() use long read for Cfg9346 register(offset 0x50) which may read
into the area of reserved register(offset 0x53). Use byte read instead.

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.
