bnx2x: Use NETIF_F_GRO_HW.
Advertise NETIF_F_GRO_HW and turn on TPA_MODE_GRO when NETIF_F_GRO_HW
is set. Disable NETIF_F_GRO_HW in bnx2x_fix_features() if the MTU
does not support TPA_MODE_GRO or GRO is not set. bnx2x_change_mtu() also
needs to disable NETIF_F_GRO_HW if the MTU does not support it.
Original parameter disable_tpa will continue to disable LRO and GRO_HW.
Preserve the original behavior of enabling LRO by default. User has
to run ethtool -K to explicitly enable GRO_HW.
