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)?

There is another, sk_user_data, that is used only by the rpc, pppol2tp,
iscsi, ncpfs, smbfs and dlm guys, see? We need a deprecate flag for
sk_protinfo, if not people will use it! :-)
