Per Forlin says:

====================
net: dsa: Make sure there is headroom for tag

Sorry for re-posting yet another time....
I manage to include multiple email-senders and forgot to include cover-letter.
Let's hope everyhthing is in order this time.

Fix two tag drivers to make sure there is headroom for the tag data.
