Hi Andrew,

Thank you for review and comments.

Hi Fahad

I expect you will find other issues with this driver. I pointed some
out at the time it is submitted, but the developers went quiet as soon
as it was accepted.

Anyway, please ensure David Miller <davem@...emloft.net> gets a copy.

The subject line should be:

[PATCH net] net: phy: Fix mask value write on gmii2rgmii converter speed register.

and include a fixes tag:

Fixes: f411a6160bd4 ("net: phy: Add gmiitorgmii converter support")
