Subject: [PATCH net-next 3/6] ice: Fix link mode handling

From: Anirudh Venkataramanan <anirudh.venkataramanan@...el.com>

The messaging for unsupported module detection is different for
lenient mode and strict mode. Update the code to print the right
messaging for a given link mode.

Media topology conflict is not an error in lenient mode, so return
an error code only if not in lenient mode.
