Subject: [support request]: where should I register this (apparently not
 supported yet) transceiver?

Hi Everyone,

I'm looking for support to register my trainsceiver in the phy subsystem.
This RJ45 transceiver (ZK-10G-TX) looks very weird in ethtool:

I cannot read its pages with i2c tools.
It has a big "AQR113C" sticker on it,
which is supported by Linux for a long time already.
I'd say it needs some quirk to activate the driver.
So, how do I verify the ZK-10G-TX has a AQR113C chip in the first place?
Does it need extra firmware? can I link it in any way to a AQR113C driver?

I am not a netdev developer, but if everything turns out like it should,
There should be a < 10line patch to let aquantia driver claim this one.

Thank you for your help,
