Re: [PATCH net v2 1/2] net: stmmac: dwmac-spacemit: Fix wrong phy interface definition

The current MII interface register definition from the vendor is wrong,
use the right number for the macro. Also, correct the interface mask
in spacemit_set_phy_intf_sel() so it can update the register with the
right number

Fixes: 30f0ba420ed3 ("net: stmmac: Add glue layer for Spacemit K3 SoC")
