Subject: [PATCH] arm64: ls1046ardb: Replace XGMII with 10GBASE-R phy mode

From: Zachary Goldstein <zachary.goldstein@...current-rt.com>

The AQR107 family does not support XGMII, but USXGMII and
10GBASE-R instead. Since ce64c1f77a9d ("net: phy: aquantia: add USXGMII
support and warn if XGMII mode is set") the kernel warns about XGMII
being used. The LS1046A SoC does not support USXGMII, so use 10GBASE-R
instead.
