Hi Portin
Nice structure. This will helper with future cleanup where C22 and C45
will be completely separated, and the c45 variants will be directly
passed dev_ad and reg, rather than have to extract them from regnum.
A few process issues.
Please read the netdev FAQ. The subject list should indicate the tree,
and there should be an patch 0/3 which explains the big picture of
what the patchset does. 0/3 will then be used for the merge commit.
