Subject: [net-next] octeontx2-pf: ethtool: Display "Autoneg" and "Port" fields

The Octeontx2/CN10k netdev drivers access a shared firmware structure
to obtain link configuration details, such as supported and advertised
link modes.

This patch updates the shared firmware data to include additional
fields like 'Autonegotiation' and 'Port type'.

example output:
  ethtool ethx
	 Advertised auto-negotiation: Yes
	 Port: Twisted Pair
