This patch eliminate special cases by adding a fast_handler member to the receive context and changes to the fast handler as specified in the new variable. Initialize the variable as soon as the setting for dma tail is known when the context is created. Setting fast path is called every time when any context has entered slow path. Add function to check if contexts is using fast path and do not set fast path when it is already done to improve RCD fastpath setting.

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.
