Add a cached FID bitmap. This mitigates the need to walk all VTU entries to find the next free FID. When flushing the VTU (during init), zero the FID bitmap. Use and manipulate this bitmap from now on, instead of reading HW for the FID map. The repeated VTU walks are costly and can take ~40 mins if ~4000 vlans are added. Caching the FID map reduces this time to <2 mins.

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 reStructuredText 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.
