Subject: [iproute2  0/1] iproute2: add TIPC statistics support in ss

The following patchset add user space TIPC socket diagnostics support
in ss tool of iproute2. It requires the sock_diag framework
for AF_TIPC support in the kernel, commit id: c30b70deb5f
(tipc: implement socket diagnostics for AF_TIPC).

tipc socket stats are requested with the "--tipc" option. Additional
tipc specific info are requested with "--tipcinfo" option.

This patchset is based on top of iproute2 v4.15.0-100-g4f63187
commitid: f85adc6. It has been co-authored by
Parthasarathy Bhuvaragan.

Example output (the first socket is the internal topology server)
# tipc-pipe  -l 1000 >&/dev/null &
# tipc-pipe --sqp -l 5003 >&/dev/null &
# tipc-pipe --rdm -l 4000 >&/dev/null &
# tipc-pipe 1000 >& /dev/null &
