Re: [PATCH net-next] net: phy: aquantia: Poll global status register for provision ID

After the firmware reset sequence completes, the global reserved status

state.

Poll VEND1_GLOBAL_RSVD_STAT1 until the provision ID field is non-zero
before returning from aqr_wait_reset_complete(). A timeout is treated as
a non-fatal warning since the PHY can still function without a valid
provision ID.

If it can still work without the provisioning ID, why bother reading
it?

Maybe extend the commit message saying what features will be missing
if there is no ID.

It looks like USXGMII and 10G-QXGMII might be mixed up? Is such a mix
up not fatal?
