Yes. I tried this test. It works as expected.

   Each LAN8651 received approximately 3Mbps with lot of "Receive buffer 
overflow error". I think it is expected as the single SPI master has to 
serve both LAN8651 at the same time and both LAN8651 will be receiving 
10Mbps on each.

Thanks for testing this.

This also shows the "Receive buffer overflow error" needs to go away.
Either we don't care at all, and should not enable the interrupt, or
we do care and should increment a counter.
