mlx5: support napi_complete_done()
A NAPI poll handler should return number of RX packets processed,
instead of 0 / budget.
This allows proper busy poll accounting through LINUX_MIB_BUSYPOLLRXPACKETS
SNMP counter.
napi_complete_done() allows /sys/class/net/ethX/gro_flush_timeout
to be used for finer GRO aggregation control.
Tested:
Enabled busy polling, and checked TcpExtBusyPollRxPackets counter is increasing.
echo 70 >/proc/sys/net/core/busy_read
nstat >/dev/null
netperf -H target -t TCP_RR >/dev/null
nstat | grep TcpExtBusyPollRxPackets
TcpExtBusyPollRxPackets 490958 0.0
