To support XDP_TX, we need to add a set of dedicated TX rings, each associated with the NAPI of an RX ring. To assign XDP rings and regular rings in a flexible way, we add a bp->tx_ring_map[] array to do the remapping. The netdev txq index is stored in the new field txq_index so that we can retrieve the netdev txq when handling TX completions. In this patch, before we introduce XDP_TX, the mapping is 1:1. v2: Fixed a bug in bnxt_tx_int(). Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

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.
