Subject: [PATCH iproute2] ss: Filter inet dgram sockets with established state by default

From: Vadim Kochan <vadim4j@...il.com>

As inet dgram sockets (udp, raw) can call connect(...)  - they
might be set in ESTABLISHED state. So keep the original behaviour of
'ss' which filtered them by ESTABLISHED state by default. So:

    $ ss -u

    or

    $ ss -w

Will show only ESTABLISHED UDP sockets by default.
