Currently, the driver code makes some assumptions about the group index and the map index of rings. This makes the code more difficult to understand and less flexible. Improve it by adding the grp_idx and map_idx fields explicitly to the bnxt_ring_struct as a union. The grp_idx is initialized for each tx ring and rx agg ring during init. time. We do the same for the map_idx for each cmpl ring. The grp_idx ties the tx ring to the ring group. The map_idx is the doorbell index of the ring. With this new infrastructure, we can change the ring index mapping scheme easily in the future. 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.
