The PHY used on the Freescale i.MX6Q/DL SABRE boards is qualified as
'rgmii' instead of 'rgmii-id'.

Can that be read two ways?
I meant the phy-mode is currently qualified as 'rgmii' instead of what it
should be: 'rgmii-id'.

I didn't put a Fixes tag in because I find this patch fixes v5.1-rc1 (which I see as broken).
But the patch is not needed in v5.0 because I see that as working.
So didn't see the need for a Cc: stable.
