[PATCH net] net: ethernet: ave: Add capability of rgmii-id mode

[Kunihiko Hayashi]

This allows you to specify the type of rgmii-id that will enable phy
internal delay in ethernet phy-mode.

I do not understand this change at all.

At a minimum you must explain things more clearly and completely in your
commit message.

Are you just adding all of the RGMII cases to the code that only currently
mentions PHY_INTERFACE_MODE_RGMII?  If so, why did you only do this for
some but not all of the get_pinmode() methods in this driver?

Thank you.

Hi David, 
Thank you for your comment.

Yes, this is intended to add all of RGMII cases to the code.
I add the cases to all of get_pinmode() except LD11, because LD11 doesn't
support RGMII due to the constraint of the hardware.

When RGMII phy mode is specified in the devicetree for LD11, the driver
will abort with the message "invalid phy-mode setting".

If it is clear, I'll add this to the next commit message.

Thank you,

Please do, thank you.
