Message-Id: <E1dGNJR-00043n-ON@rmk-PC.armlinux.org.uk>
Date: Thu, 01 Jun 2017 11:26:41 +0100
From: Russell King <rmk+kernel@...linux.org.uk>

Subject: [PATCH 3/5] net: phy: split out 10G genphy support
Move the old 10G genphy support to sit beside the new clause 45 library
functions, so all the 10G phy code is together.
Signed-off-by: Russell King <rmk+kernel@...linux.org.uk>
