Mugunthan

Can you confirm that I'm actually trying to achieve the right thing ?

I have all along assumed that Dual EMAC mode would simply provide the
kernel will a pair of independent Ethernet ports.

All I am trying to do is to get both Ethernet ports working so I can
have one port on (say) 10.0.x.x and the other on (say) 10.1.x.x

But there is all this reference to VLANs(in the source code and the TRM)
... I have not setup any VLANs.  Do I need to ?  If so, how ?

Cheers
Mark J.
