From: Lendacky, Thomas Date: Fri, 20 Mar 2015 16:49:42 +0000 (-0500) Subject: amd-xgbe-phy: Use phydev advertising field vs supported X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d9663c8c2149;p=deliverable%2Flinux.git amd-xgbe-phy: Use phydev advertising field vs supported With ethtool being able to control what is advertised, the advertising field is what should be used for priming the auto-negotiation registers and for various other checks, instead of the supported field. Also, move the initial setting of the supported and advertising fields into the probe function so that they are not reset each time the device is brought up, thus allowing the user to set as desired before bringing the device up.
