Joe Damato says: ==================== mlx4: Add support for netdev-genl API There are no functional changes from v5, which I mistakenly sent right after net-next was closed (oops). This revision, however, includes Tariq's Reviewed-by tags of the v5 in each commit message. See the changelog below. This series adds support to mlx4 for the netdev-genl API which makes it much easier for users and user programs to map NAPI IDs back to ifindexes, queues, and IRQs. This is extremely useful for a number of use cases, including epoll-based busy poll. In addition, this series includes a patch to generate per-queue statistics using the netlink API, as well. To facilitate the stats, patch 1/3 adds a field "alloc_fail" to the ring structure. This is incremented by the driver in an appropriate place and used in patch 3/3 as alloc_fail. Please note: I do not have access to mlx4 hardware, but I've been working closely with Martin Karsten from University of Waterloo (CC'd) who has very graciously tested my patches on their mlx4 hardware (hence his Tested-by attribution in each commit). His latest research work is particularly interesting [1] and this series helps to support that (and future) work. Martin re-test v4 using Jakub's suggested tool [2] and the stats.pkt_byte_sum and stats.qstat_by_ifindex tests passed. He also adjusted the queue count and re-ran test to confirm it still passed even if the queue count was modified.

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.
