[patch 38/86] 8139cp: fix missing napi_gro_flush.

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Francois Romieu <romieu@xxxxxxxxxxxxx>

commit b189e810619a676e6b931a942a3e8387f3d39c21 upstream.

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.
