If you want to configure the RGMII delays in the vsc73xx MAC, you should
look at the "rx-internal-delay-ps" and "tx-internal-delay-ps" properties
in the MAC OF node, rather than at the phy-mode. The phy-mode is for the
internal delays from the PHY.

In any case, you should accept any phy_interface_is_rgmii() regardless
of whether internal delays are configurable in the MAC. And yes, parsing
those MAC OF properties should be a separate change.

If the series exceeds 15 patches, I would consider splitting it per
topic and submitting separate series (link management would be one,
tag_8021q/bridging/VLAN would be another). If they don't conflict and
can be applied independently, you could also send the 2 series
simultaneously.
