Nikolay Aleksandrov 85b4108211 net: bridge: mcast: dump ipv6 querier state
Add support for dumping global IPv6 querier state, we dump the state
only if our own querier is enabled or there has been another external
querier which has won the election. For the bridge global state we use
a new attribute IFLA_BR_MCAST_QUERIER_STATE and embed the state inside.
The structure is:
  [IFLA_BR_MCAST_QUERIER_STATE]
   `[BRIDGE_QUERIER_IPV6_ADDRESS] - ip address of the querier
   `[BRIDGE_QUERIER_IPV6_PORT]    - bridge port ifindex where the querier
                                    was seen (set only if external querier)
   `[BRIDGE_QUERIER_IPV6_OTHER_TIMER]   -  other querier timeout

IPv4 and IPv6 attributes are embedded at the same level of
IFLA_BR_MCAST_QUERIER_STATE. If we didn't dump anything we cancel the nest
and return.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
