Since commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for RGMII mode") the networking is broken on the BeagleBone AI which has the AR8035 PHY for Gigabit Ethernet [0]. The fix is to switch from phy-mode = "rgmii" to phy-mode = "rgmii-rxid". Note: Grygorii made a similar DT fix for other AM57xx boards with a different phy in commit 820f8a870f65 ("ARM: dts: am57xx: fix networking on boards with ksz9031 phy").
