Subject: [PATCH v4 2/3] net: phy: Encapsulate actions performed during link state changes into function phy_adjust_link
Date: Tue, 11 Oct 2016 15:26:19 -0500 [thread overview]
Message-ID: <1476217580-21229-3-git-send-email-zach.brown@ni.com> (raw)
In-Reply-To: <1476217580-21229-1-git-send-email-zach.brown@ni.com>
During phy state machine state transitions some set of actions should
occur whenever the link state changes. These actions should be
encapsulated into a single function
This patch adds the phy_adjust_link function, which is called whenever
phydev->adjust_link would have been called before. Actions that should
occur whenever the phy link is adjusted can now be added to the
phy_adjust_link function.
