Subject: [PATCH 3/4] net: phy: extract pause mode

From: Russell King <[email-masked]>
Date: Sun, 22 Sep 2019 12:00:20 +0100

Extract the update of phylib's software pause mode state from
genphy_read_status(), so that we can re-use this functionality with
PHYs that have alternative ways to read the negotiation results.
