Add support for group stats for mac. The fbnic_set_counter help preserve the default values for counters which are not touched by the driver. The 'reset' flag in 'get_eth_mac_stats' allows to choose between resetting the counter to recent most value or fetching the aggregated values of the counter. The 'fbnic_stat_rd64' read 64b stats counters in an atomic fashion using read-read-read approach. This allows to isolate cases where counter is moving too fast making accuracy of the counter questionable.

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 reStructuredText 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.
