mainlining shenanigans

Instead of offering the user space given receive buffer size to the crypto card firmware as limit for the reply message offer the internal per queue reply buffer size. As the queue's reply buffer is always adjusted to the max message size possible for this card this may offer more buffer space. However, now it is important to check the user space reply buffer on pushing back the reply. If the reply does not fit into the user space provided buffer the ioctl will fail with errno EMSGSIZE.

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.
