Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY") the networking is broken on keystone-k2g-evm board.
The above board have phy-mode = "rgmii-id" and it is worked before because
KSZ9031 PHY started with default RGMII internal delays configuration (TX
off, RX on 1.2 ns) and MAC provided TX delay by default.
After above commit, the KSZ9031 PHY starts handling phy mode properly and
enables both RX and TX delays, as result networking is become broken.
Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous
behavior.

Fix for one more broken TI board with KSZ9031 PHY.
Can you please apply this patch to your v5.8 fixes branch and send it
upstream ? Without the fix K2G EVM board is broken with v5.8.
Am hoping you can pick this up with pull request since it just one
patch.
Regards,
Santosh
