Subject: Re: [PATCH net-next] net: phy: at803x: fix PHY ID masks

> Ever since its first commit 0ca7111a38f05 ("phy: add AT803x driver") the
> PHY ID mask was set to 0xffffffef. It is unclear to me why this mask was

>  - for AR8035 its 0x004d/0xd072
> Unfortunately, I don't have a datasheet for the AR8030. Therefore, we
