Merge branch 'mvneta-some-small-improvements'
Jisheng Zhang says: ==================== net: mvneta: some small improvements patch1 removes the NETIF_F_GRO check ourself, because the net subsystem will handle it for us. patch2 enables NETIF_F_RXCSUM by default, since the driver and HW supports the feature. patch3 is a small optimization, to reduce smp_processor_id() calling in mvneta_tx_done_gbe. since v1: - based on net-next tree - remove the fix patches, since they should be based on net branch. - Add Gregory's Reviewed-by tag ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
