Subject: net: phy: motorcomm: Optimize phy speed mask to be compatible to YT8821
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=a1211a5f6bf655ca039988e3501e85e1f27078c6;p=u-boot.git

net: phy: motorcomm: Optimize phy speed mask to be compatible to YT8821

YT8531 as Gigabit transceiver uses bit15:14(bit9 reserved default 0) as phy
speed mask, YT8821 as 2.5 Gigabit transceiver uses bit9 bit15:14 as phy
speed mask.

Be compatible to YT8821, reform phy speed mask and phy speed macro.
