* Added defines for TX Event FIFO Element * Adapted ndo_start_xmit function. For versions >= v3.1.x it uses the TX FIFO to optimize the data throughput. It stores the echo skb at the same index as in the M_CAN's TX FIFO. The frame's message marker is set to this index. This message marker is received in the TX Event FIFO after the message was successfully transmitted. It is used to echo the correct echo skb back to the network stack. * Added m_can_echo_tx_event function. It reads all received message markers in the TX Event FIFO and loops back the corresponding echo skbs. * ISR checks for new TX Event Entry interrupt for version >= 3.1.x.

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.
