This device uses an AR8031/AR8033 chip to convert SoC gmac1
RGMII to 1000base-x or sgmii for the SFP fibre cage.
The SFP cage requires phy-mode rgmii-rxid, and without it will not
recieve any packets: ethtool -S sfp rx_fcs_errors will increase when
packets should be being received, but no other _rx counters will change.
Fixes: c77858aa79 ("ramips: mt7621-dts: change phy-mode of gmac1 to rgmii")
