Hi Raghuram

What do you expect is connected to the MAC if there is no PHY?

Hi Andrew,
We connect the Ethernet switch to this MAC. The Ethernet switch port connected 
to MAC do not have the phy.
In this case, need to load the MAC driver and link speed/duplex set.

Ah, cool. I was thinking you were going to say an SFP cage.

What switch is it? Does it have a DSA driver?

We have 3 port switch KSZ9893 yet to release which is similar to the one 
KSZ9477/KSZ9897 which has DSA driver.
Most of the time 3 port switch being used with LAN7801 to extend the ports.
