Nah, it still there, sk_protinfo, its just ax25 that uses it
(nudge(Ralf)). How do we state that a struct field is deprecated and
will be removed soon(tm)?

You get rid of all the in-tree users and then just kill it :)

More seriously, I don't think we need a deprecation schedule
for a struct member, either it's not used in-tree anymore or
it isn't.  We'll go crazy with any other policy and it's
difficult enough shrinking these things :-)
