The flexcan IP core has 64 mailboxes. For now they are configured for RX as a hardware FIFO. This FIFO has a fixed depth of 6 CAN frames. In some high load scenarios it turns out thas this buffer is too small. In order to have a buffer larger than the 6 frames FIFO, this patch adds support for timestamp based offloading via the generic rx-offload infrastructure.

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.
