Currently when a querier port is detected its net_bridge_port pointer is recorded, but it's used only for comparisons so it's fine to have stale pointer, in order to dereference and use the port pointer a proper accounting of its usage must be implemented adding unnecessary complexity. To solve the problem we can just store the netdevice ifindex instead of the port pointer and retrieve the bridge port. It is a best effort and the device needs to be validated that is still part of that bridge before use, but that is small price to pay for avoiding querier reference counting for each port/vlan.

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.
