Hi,
For some reason I still haven't received patch 01 which adds this new flag,
so I'll comment on this patch first.

These should be 2 separate patches, there is no bridge: dsa:.
Please break them into a bridge: and dsa: parts that add the flag, it also
makes it easier for people who have to backport patches and fixes later.

In addition please mention in the commit message why the flag is
added there, i.e. in order to allow to be offloaded.

Thanks,
 Nik
