Add two new parameters: max_burst_sz and typical_pkt_size (both in bytes) to rate limit configurations. max_burst_sz: The device will schedule bursts of packets for an SQ connected to this rate, smaller than or equal to this value. Value 0x0 indicates packet bursts will be limited to the device defaults. This field should be used if bursts of packets must be strictly kept under a certain value. typical_pkt_size: When the rate limit is intended for a stream of similar packets, stating the typical packet size can improve the accuracy of the rate limiter. The expected packet size will be the same for all SQs associated with the same rate limit index. Ethernet driver is updated according to this change, but these two parameters will be kept as 0 due to lacking of proper way to get the configurations from user space which requires to change ndo_set_tx_maxrate interface.

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.
