nfp: ethtool: support reporting link modes

Browse source

[ Upstream commit a61474c41e ]

Add support for reporting link modes,
including `Supported link modes` and `Advertised link modes`,
via ethtool $DEV.

A new command `SPCODE_READ_MEDIA` is added to read info from
management firmware. Also, the mapping table `nfp_eth_media_table`
associates the link modes between NFP and kernel. Both of them
help to support this ability.
