Subject: Re: [EXT] [PATCHv3] ethernet: aquantia: Try MAC address from device tree
Date: Wed, 1 Dec 2021 09:12:25 +0100	[thread overview]
Message-ID: <374a236a-4fd1-b21a-5dc2-c123204eb593@marvell.com> (raw)

Hi Tianhao,

> Apple M1 Mac minis (2020) with 10GE NICs do not have MAC address in the
> card, but instead need to obtain MAC addresses from the device tree. In
> this case the hardware will report an invalid MAC.
> 
> Currently atlantic driver does not query the DT for MAC address and will
> randomly assign a MAC if the NIC doesn't have a permanent MAC burnt in.
> This patch causes the driver to perfer a valid MAC address from OF (if
> present) over HW self-reported MAC and only fall back to a random MAC
> address when neither of them is valid.
