In Striding RQ, each WQE serves multiple packets (hence called Multi-Packet WQE, MPWQE). The size of a MPWQE is constant (currently 256KB). Upon a ringparam set operation, we calculate the number of MPWQEs per RQ. For this, first it is needed to determine the number of packets that can reside within a single MPWQE. In this patch we use the actual MTU size instead of ETH_DATA_LEN for this calculation. This implies that a change in MTU might require a change in Striding RQ ring size. In addition, this obsoletes some WQEs-to-packets translation functions and helps delete ~60 LOC. Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
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.
