Add support for the ethtool get_link and get_link_ksettings
operations. Display standard port information using ethtool.

Before the change:
$ethtool enP30832s1

After the change:
$ethtool enP30832s1

Hi Erni, Haiyang, all

Thanks for the update, it looks like it addresses the review of v1 by Jakub.
However, I am assuming that as a non-bug-fix, this is targeted at net-next.
And net-next is currently closed for the v6.12 merge window.  Please
consider reposting this patch once net-next reopens.  That will occur after
v6.12-rc1 has been released.  Which I expect to be about a week from now.

Also, for networking patches please tag non-bug fixes for
net-next (and bug fixes for net, being sure to include a Fixes tag).

	Subject: [PATCH net-next] ...

Please see https://docs.kernel.org/process/maintainer-netdev.html
