net: netcp: fix forward port number usage for 10G ethss
10G switch requires forward port number in the taginfo field,
where as it should be in packet_info field for necp 1.4 Ethss. So
fill this value correctly in the knav dma descriptor.
Also rename dma_psflags field in struct netcp_tx_pipe to switch_to_port
as it contain no flag, but the switch port number for forwarding the
packet. Add a flag to hold the new flag, SWITCH_TO_PORT_IN_TAGINFO which
will be set for 10G. This can also used in the future for other flags for
the tx_pipe.
