Added new option 'type' to 'ip link show'
command which allows to filter devices by type:
ip link show type bridge
ip link show type vlan

Sometimes it's needed to have "ip address show" list only addresses
with certain flags not being set, e.g. in network scripts.
As an example one might want to exclude addresses in "tentative"
or "deprecated" state.
Support listing addresses with flags tentative, deprecated, dadfailed
not being set by prefixing the respective flag with a minus.

Checking by SS_CLOSE state was remowed in:
(45a4770bc0) ss: Remove checking SS_CLOSE state for packet and netlink
which is not really correct because now by default all sockets are seen
when do 'ss'.
Here is most correct fix which considers specified family.
To see netlink sockets:
ss -A netlink
To see packet sockets:
ss -A packet
And ss by default will show only connected/established sockets as it
was before all the time.

Replaced handling netlink messages by rtnl_dump_filter
from lib/libnetlink.c, also:
- removed unused dump_fp arg;
- added MAGIC_SEQ #define for 123456 seq id;
- silently exit if ENOENT errno is caused for NETLINK_SOCK_DIAG proto
in lib/libnetlink.c: rtnl_duml_filter_l(...) function. This fix
was added in a3fd8e58c1 by Eric
for misc/ss.c

This patch fixes the following issues which was introduced by me in commits:
#1 (2dc854854b) ss: Fixed broken output for Netlink 'Peer Address:Port' column
ISSUE: Broken layout when all sockets are printed out
#2 (eef43b5052) ss: Identify more netlink protocol names
ISSUE: Protocol id is not printed if 'numbers only' output was specified (-n)
Also aligned the width of the local/peer ports to be more wider.
I tested with a lot of option combinations (I may miss some test cases),
but layout seems to me better than the previous released version of iproute2/ss.

The issue was observed when IPv6 router broadcasted NDUSEROPT
messages which are not handled by monitor and caused printing
'Timestamps' w/o message because such kind of rtnl messages is not
handled by monitor.
As 'ip monitor' by default subscribes to the all mcast rtnl groups except
RTGRP_TC then all messages of these rtnl groups which are not handled by
monitor may cause such issues.
Fixed by subscribing by default to rtnl mcast groups which are
supported by 'ip monitor'.

This option was used only for 'ip link', but it can be useful to have it for
'ip address'. Thus it is possible to display link details and addresses with one
command.

Add NTF_EXT_LEARNED flag to neigh flags to indicate FDB entry learned by
device has been learned externally to bridge FDB. For these entries,
add "external" annotation in bridge fdb show output:
00:02:00:00:03:00 dev swp2 used 2/2 master br0 external
00:02:00:00:03:00 dev swp2 self permanent
In the example above, 00:02:00:00:03:00 is shown twice on dev swp2. The
first entry if from the bridge (master) and is marked as "external" by
the offload device. The second entry is from the brport offload device (self),
and was learned by the device.

This permits to selectively enable explicit congestion notification via
the routing table.
If this ecn feature is not set, the kernel will use the tcp_ecn sysctl
to decide wheter to use ECN when establising a TCP connection.
At the time of this writing, the kernel supports ecn and allfrags, but
allfrags is of dubious value and not implemented here.
Example:

I dont see a reason that packet and netlink states will be
printed only if SS_CLOSE state is set in filter, in that case
to print states of netlink or packet sockets it is needed to run:
ss -A netlink state close
instead of:
ss -A netlink
