The refcount is done via entry->skb, which does work fine. Major problem: When putting the refcount of the bridge ports, we must always put the references while the skb is still around. However, we will need to put the references after okfn() to avoid a possible 1 -> 0 -> 1 refcount transition, so we cannot use the skb pointer anymore. Place the physports in the queue entry structure instead to allow for refcounting changes in the next patch.

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.
