no worries. thanks for submitting the patch Jiri.

One thing though (Which i also mentioned in one of the threads on this),
the below command will not work with layered devices with the below patch.
Because 'self' commands will directly try to find the switch port driver 
from
rtnetlink.c and they dont use the switch dev api.

bridge link set dev bond0 learning off self

The code that currently exists in the tree with bond and team supporting 
the op
will actually work.

If you agree with the above, I can rethink how this can be made to work 
with the 'self'
indirection from rtnetlink.c and still use transparent lowerdev 
traversal and resubmit.
Or if you prefer to resubmit, you can.

Thanks,
Roopa
