We were using t4_get_mps_bg_map() for both t4_get_port_stats() to determine which MPS Buffer Groups to report statistics on for a given Port, and also for t4_sge_alloc_rxq() to provide a TP Ingress Channel Congestion Map. For T4/T5 these are actually the same values (because they are ~somewhat~ related), but for T6 they should return different values (T6 has Port 0 associated with MPS Buffer Group 0 (with MPS Buffer Group 1 silently cascading off) and Port 1 is associated with MPS Buffer Group 2 (with 3 cascading off)).

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.
