> Subject: [XGMAC RGMII-ID fix v1 1/1] net: dwc_eth_xgmac_socfpga: Add
> support for rgmii-id mode.
>
> An issue was identified where selecting the phy-mode as rgmii-id in the
> device tree source (DTS) would cause the `dwc_eth_xgmac_socfpga` driver
> to raise an unsupported phy mode error.
>
> From the MAC controller's perspective, the rgmii and rgmii-id phy modes are
> effectively identical. To address this, both modes will now be configured to
> rgmii in the MAC controller.
>
> This change ensures that the rgmii-id phy mode is properly supported
> without error.
