PATCH 2/2 net: ethernet: nb8800: handle all RGMII declinations

Commit a999589ccaae ("phylib: add RGMII-ID interface mode definition") and commit 7d400a4c5897 ("phylib: add PHY interface modes for internal delay for tx and rx only") added several RGMII declinations:
PHY_INTERFACE_MODE_RGMII_ID, PHY_INTERFACE_MODE_RGMII_RXID and PHY_INTERFACE_MODE_RGMII_TXID to deal with internal delays.

Those are all RGMII modes (1Gbit) and must be considered that way when setting the MAC Mode or the Pads Mode for the HW to work properly.

This part is correct regardless of the outcome of the delay setup discussion.

You cannot just repost one part of a patch series when you make changes.

You must always repost the entire series as a new fresh version, with changelog entries added to your "[PATCH v2 0/2] ..." header posting.

Thanks for the information.

I sent v2, and then v3, because v2 had formatting issues, hopefully it is ok now.

Best regards,

Sebastian
