From 796d709363135a6bd6a8ccc07b509c939e5b855f Mon Sep 17 00:00:00 2001
From: "Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>

Subject: [PATCH 19/21] net: phylink: provide phylink_pcs_config() and
phylink_pcs_link_up()
Add two helper functions for calling PCS methods. phylink_pcs_config()
allows us to handle PCS configuration specifics in one location, rather
than the two call sites. phylink_pcs_link_up() gives us consistency.
