Subject: net: macb: Fixed reading MII_LPA register
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1b0c9914cc75d1570359181ebd493cd5746cb0ed;p=u-boot.git

net: macb: Fixed reading MII_LPA register

If macb is gem and is gigabit capable, lpa value is not read from
the right register(MII_LPA) and is read from MII_STAT1000. This patch
fixes reading of the lpa value.
