Does LS1028A processor support the “half QSGMII” feature required by VSC8562-11 QSGMII PHY?

[Nithya]

In our project we are interfacing VSC8562-11 QSGMII PHY to the LS1028A processor's TSN switch SerDes port.

VSC8562-11 is a Dual-Port 10/100/1000BASE-T PHY and in its datasheet we observed as follows: 

Two of the four QSGMII channels contain data. The windows for the other two channels remain present
and need to be supported in both directions by the MAC. This support is called “half QSGMII.”

Can you please confirm me that LS1028A processor supports this “half QSGMII” feature?

LS1028A supports QSGMII.

According to the PHY datasheet it also supports QSGMII, so physical interface should work.

The feature was not tested, but using two MACs of available four should not introduce a trouble.
