Subject: [net-next  8/9] igb: Implementation to report advertised/supported link on i354 devices

From: Akeem G Abodunrin <akeem.g.abodunrin@...el.com>

This patch changes the way we report supported/advertised link for i354
devices, especially for 2.5 GB. Instead of reporting 2.5 GB for all i354
devices erroneously, check first, if it is 2.5 GB capable.
