Hi Dan

I think you are going to have to add
ETHTOOL_LINK_MODE_10baseT1_Full_BIT? We already have 100T1 and 1000T1,
but not 10T1 :-(
The data sheet says 10baseT1L.  Which is not there either and seems to be
the latest 802.3cg spec and has a greater max distance and used for IoT and
Automotive.
Hi Dan

Do you know anything about interropibility? Can a T1 and a T1L talk to
each other, if suitably close? I'm wondering if this device should say
it is both T1 and T1L? Or just T1L?

I personally don't know about interoperability my tests were T1L to T1L but I forwarded these questions to my HW PHY team.
