This patch converts the flexcan driver to make use of the rx-offload can_rx_offload_irq_offload_fifo() helper function. The idea is to read the CAN frames already in the interrupt context, as the depth of the flexcan HW FIFO is too shallow, resulting in too many missed frames. During a normal NAPI poll the frames are the pushed into the upper layers. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
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.
