Re: Aquantia PHY in OCSGMII mode?

I don see any firmware problems. I have one of the latest builds, and from what
I understand, the firmware consists of base image and additionally a
provisioning table. But this table is a kind of pre-configuration. That means I
can override the entire PHY configuration to my needs.
This pre-configuration is what i don't like about these PHYs. It means
you cannot assume any register has the value the datasheet says it
should have after a reset. The driver might work for you, but not for
others because your firmware has different pre-configurations to other
firmware. So in effect, the driver needs to write every single
register with a known value...
