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 Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Eli Cohen <eli@mellanox.com> Signed-off-by: David S.
