You could extend and use ethtool.  That is what it's there for.

The IOCTLs I need are very specific and will only be used for
the redirect module.  I don't think it would be worth adding
a function pointer to the ethtool-ops, but if that is what you
prefer I can do so.

I'll let Jeff make this call.

With regard to the compat:  I did a quick search for 'vlan' in that
file, thinking I'd mimic whatever was done for the .1q module.  There
is no mention of vlan anywhere in there.

fs/compat_ioctl.c includes some files, perhaps you should check
some of those out.  In particular, what you seek might, just might,
be discoverd in include/linux/compat_ioctl.h
