That goes to the series of switches via SGMII on the "media" side of the phy. RGMII_SGMII mode is enabled via devicetree register descriptions. The switch on the "media" side has auto-negotiation disabled, so configuration from userspace similar to: ethtool -s eth0 autoneg off speed 1000 duplex full is necessary to get traffic flowing on that interface. ethernet1 is in a mac2mac/fixed-link configuration going to the same series of switches directly via RGMII.
