This series contains Misc updates and cleanups for mlx5e rx path
and SQ recovery feature for tx path.
From Tariq: (RX updates)
- Disable Striding RQ when PCI devices, striding RQ limits the use
of CQE compression feature, which is very critical for slow PCI
devices performance, in this change we will prefer CQE compression
over Striding RQ only on specific "slow" PCIe links.
- RX path cleanups
- Private flag to enable/disable striding RQ
From Eran: (TX fast recovery)
- TX timeout logic improvements, fast SQ recovery and TX error reporting
if a HW error occurs while transmitting on a specific SQ, the driver will
ignore such error and will wait for TX timeout to occur and reset all
the rings. Instead, the current series improves the resiliency for such
HW errors by detecting TX completions with errors, which will report them
and perform a fast recover for the specific faulty SQ even before a TX
timeout is detected.
Thanks,
Saeed.

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.
