Hi All,

I'm starting to look at some L2/L3 switches with Realtek silicon. I see
in the upstream kernel there are dsa drivers for a couple of simple L2
switches. While openwrt has support for a lot of the more advanced
silicon. I'm just wondering if there is a particular reason no-one has
attempted to upstream support for these switches? If I were to start
grabbing drivers from openwrt and trying to get them landed would that
be a problem?

Thanks,
Chris

What do you mean by the L3 switching functionality, exactly? Offloading
of inter-VLAN routing? Or routing offload in general?

Offloading of inter-VLAN routing. There's also some multicast and qos 
capability too.

I gather the general idea is to provide mechanisms for the hardware to 
accelerate parts of the forwarding plane. I haven't got into the details 
of that yet, my first set of requirements is just around basic L2 
switching which I think is pretty well supported at this point.
