Eric Dumazet 24d2e4a507 tg3: use napi_complete_done() 
Using napi_complete_done() instead of napi_complete() allows
us to use /sys/class/net/ethX/gro_flush_timeout

GRO layer can aggregate more packets if the flush is delayed a bit,
without having to set too big coalescing parameters that impact
latencies.

Tested:

lpx:~# echo 0 >/sys/class/net/eth1/gro_flush_timeout
