Subject: [net-next 14/15] i40e/i40evf: Retrieve and store missing link config information

From: Neerav Parikh <Neerav.Parikh@...el.com>

Some information returned via "Get Link Status" command was not
being cached in the struct i40e_link_status.
Add this so the driver can utilize this information as needed.
