Hi Alexey,

thanks for you review, I'll post v3 with your changes.

I got these errors:
* -c (TI-RPC tests)
rpc_clnt_broadcast 1 TBROK: 'rpc_clnt_broadcast 10.0.0.2 536875000 ' failed on '': 'RPC: Timed out

I tested it with libtirpc3 1.0.1-3 from Tumbleweed and with libtirpc1 0.2.5-1.1 on Debian
testing.
I wonder whether 'svc_fd_create: could not retrieve local addr' which comes from libtirpc
[1] is our bug or libtirpc bug or netns bug.
BTW there is also another library called ntirpc, which might be useful to test [2].
