As of current design, in each NAPI, only a single UMR WQE completion could be available in the completion queue of the the internal control operations (ICO) send queue, in addition to nop operations that require no actions upon completion. This renders the consume index obsolete, as the wqe_counter field in CQE is sufficient. This helps removing a memory barrier, and obsoletes the need for tracking the num_wqebbs to update the consumer counter. In addition, remove other unused fields in icosq struct: pdev, dma_fifo_pc, and prev_cc. 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.
