Subject: [PATCH 5.4 39/40] i40e: Add additional info to PHY type error

From: Lukasz Cieplicki <lukaszx.cieplicki@...el.com>

commit dc614c46178b0b89bde86ac54fc687a28580d2b7 upstream.

In case of PHY type error occurs, the message was too generic.
Add additional info to PHY type error indicating that it can be
wrong cable connected.

Fixes: 124ed15bf126 ("i40e: Add dual speed module support")
