After commit bf9765145b85 ("sock: Make sk_protocol a 16-bit value")
the current size of 'sdiag_protocol' is not sufficient to represent
the possible protocol values.
This change introduces a new inet diag request attribute to let
user space specify the relevant protocol number using u32 values.
The attribute is parsed by inet diag core on get/dump command
and the extended protocol value, if available, is preferred to
'sdiag_protocol' to lookup the diag handler.
The parse attributed are exposed to all the diag handlers via
the cb->data.
Note that inet_diag_dump_one_icsk() is left unmodified, as it
will not be used by protocol using the extended attribute.
