Subject: [PATCH AUTOSEL 4.19 35/73] arm64: dts: renesas: condor: switch from EtherAVB to GEther

From: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>

[ Upstream commit eab53fdfd60a84b0cc514d4f1f5d79226c76df01 ]

The "official" Condor boards have always been wired to mount NFS via
GEther, not EtherAVB -- the boards resoldered for EtherAVB were local
to Cogent Embedded, so we've been having an unpleasant situation where
a "normal" Condor board still can't mount NFS (unless an EtherAVB PHY
extension board is plugged in). Switch from EtherAVB to GEther at last!

Fixes: 8091788f3d38 ("arm64: dts: renesas: condor: add EtherAVB support")
