This patch reduces the usage of the write channel's static cmd buffers, by dynamically allocating all simple IPA cmds (eg. STARTLAN, SETVMAC). It also converts the OSN path. Doing so requires some changes to how we calculate the cmd length. Currently when building IPA cmds, we're quite generous in how much data we send down to the device (basically the size of the biggest cmd we know). This is no real concern at the moment, since the static cmd buffers are backed with zeroed pages. But for dynamic allocations, the exact length matters. So this patch also adds the needed length calculations to each cmd path. Commands that have multiple subtypes (eg. SETADP) of differing length will be converted with follow-up patches.

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.
