unsigned char for an enum is really odd.

Sure, sorry the context got lost.
We want to expose the origin of ifnames so that udev can better decide
whether or not to rename them. In particular, this patch will allow
udev to tell that it should no longer rename Wifi-P2P devices, which
is currently a problem.
A general overview is in the patch introducing the interface:
<http://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git/commit/?id=685343fc3ba61a1f6eef361b786601123db16c28>.

Hm, this was based on the addr_assign_type attribute, which also is an
unsigned char (and serves a very similar purpose).
Out of interest, what would you have preferred (and why)?
Cheers,

Even if it eventually ends up being assigned to a u8 or something, it
seems passing it around as an enum makes the interfaces better?

name is used, so set NET_NAME_ENUM.

The indentation is now not correct. For a function call, all arguments on the
second and subsequent line, must start exactly at the first column after the
openning parenthesis of the function call.

Indeed. Thanks, I'll fix this up.

The ifname is of the form pppX where X is the unit number. This is either set
by userspace, or userspace requests the kernel to chose one, which is then
returned to userspace. Either way the creating user knows the name, so we
treat both cases as if the user had explicitly chosen the name and label
it NET_NAME_USER.
