Currently, FlexRM driver uses txdone_poll method of Linux Mailbox to model the send_data() callback. To achieve this, we have introduced "last_pending_msg" pointer for each FlexRM ring which keeps track of the message that did not fit in the FlexRM ring. This patch updates FlexRM driver to use txdone_ack method instead of txdone_poll method because txdone_poll is not efficient for FlexRM and requires additional tracking in FlexRM driver. Also, moving to txdone_ack method helps us remove "last_pending_msg" pointer and last_tx_done() callback.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
