wait, why kirkwood?
I have one of the two kirkwood devices with a switch, running snapshot 
and it's definitely been using DSA for a while

Checking the kernel config....

CONFIG_HAVE_NET_DSA=y

and there is no CONFIG_SWCONFIG

Yes it is using DSA.

The commit to move kirkwood to DSA is

4fd7e539e4f90128bdd7cb71c729a4b32f5de86e

from April 28
