  I'm trying to write a pseudo interface, but I'm confused about
my responsibilities for the _ioctl() command.

  It seems that for the assigning of an address, I simply need to
return 0 to indicate that address family is ok, as the higher level
functions handle the actuall assignment of addresses. Is this true?
Do I need to do anything else, such as installing routes into the
routing table (if I don't want the user to have to run route commands
for it).

  Is my interface responsible for any other SIOC's, or can it safely
return EINVAL or 0 for SIOC's it doesn't recognize? (Apart from any
SIOC's that I custom define of course)

  Thanks
  Geoff
