Refactor HW statistics which, - Unifies HW statistics support for all HW generations. - Unifies support of 32- and 64-bit counters. - Removes duplicated code and simplifies implementation. - Fixes roll-over handling. - Removes unneeded last_hw_stats. With new implementation, there is no separate handling and no separate arrays for 32- and 64-bit counters (offsets, regs, values). Instead, there is a HW stats map array for each HW revision, which defines HW-specific width and location of each counter in the statistics buffer. Once the statistics are gathered (either via CQP op, or by reading HW registers), counter values are extracted from the statistics buffer using the stats map and the delta between the last and new values is computed. Finally, the counter values in rdma_hw_stats are incremented by those deltas. From the OS perspective, all the counters are 64-bit and their order in rdma_hw_stats->value[] array, as well as in irdma_hw_stat_names[], is the same for all HW gens. New statistics should always be added at the end.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
