100GbE Intel Wired LAN Driver Updates 2019-08-20
This series contains updates to ice driver only.
Brett fixes the detection of a hung transmit ring by checking the
software based tail (next_to_use) to determine if there is pending work.
Updates the driver to assume that using more than one receive queue per
receive ring container is a rare case, so use unlikely() in the case
were we actually need to divide our budget for multiple queues. Fixed
an issue where the write back on ITR bit was not being set when
interrupts are disabled, which was causing only write backs when polling
only when a cache line is filled. Cleans up unnecessary wait times
during VF bring up and reset paths. Increased the mailbox size for
receive queues that are used to communicate with VFs to accommodate the
large number of VFs that the driver can support.
Akeem restructures the initialization flows for VFs, including how VFs
are configured and resources allocated to improve flows so that when we
clean up resources, we do not try to free resources that were never
allocated. Organizes code to ensure that VF specific code is located in
the SR-IOV specific file.
Paul fixes an issue when setting the pause parameter which was
incorrectly blocking users from changing receive or transmit pause
settings. Ensure register access for MSIX vector index is only done in
the PF space and not absolute device space.
Usha fixes a potential kernel hang in the DCB rebuild path when in CEE
mode, where the ETS recommended DCB configuration is not being set or
set correctly.
Mitch updates the driver to process all receive descriptors, regardless
of the size of the associated data.
Tony fixes and issue during the reset/rebuild path of a PF VSI where we
were assuming that the PF VSI was always to be enabled, which can
attempt to bring up a PF VSI on a downed interface which can lead to
various crashes.
Pawel fixes up variable definitions to match the type of data being
stored.
v2: Dropped patch 1 of the series to add ethtool support to query/add
channels on a VSI, while we re-qork the functionality to match the
ethtool expected behavior to report combined (Tx and Rx) numbers.
v3: Updated patch 4 to use kzalloc() and kfree() instead devm_kzalloc()
and devm_kfree().

README
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.
