====================
40GbE Intel Wired LAN Driver Updates 2016-08-19

This series contains updates to i40e and i40evf only.

Jake provides several patches, first just moves a function to co-locate
the two functions related to configuring RSS via the admin queue, which
should help in spotting bugs when comparing the two functions.  Fixed
an issue where commit e69ff813af ("i40e: rework the functions to
configure RSS with similar parameters") missed checking whether the seed
is NULL before using it and did not use the passed in *lut parameter.
Fixed an issue where a previous refactor missed i40e_vsi_config_rss()
and the values were being ignored, so checked for the fields and used
them instead of default values.  Lastly replaced calls to
create_singlethread_workqueue() with alloc_workqueue() to provide more
control over workqueue creation and allows explicit setting of the
desired mode of operation.

Mitch adds link speed to log messages and reports speed through ethtool.

Carolyn refactors tail bump check and fixes byte ordering problems found
when enabling this feature support.  Adds support for HMC resources and
profile commands for x722 firmware.

Heinrich Schuchardt fixes format identifiers from %u to %d since the
variable is defined as an integer.

Catherine fixes an issue where there was a race condition between the
completion of the client open and calls to the client ops, so ensured
that client ops are not called until we are sure client is open.

Harshitha makes sure that i40e_client_release() does not try to use
an adapter pointer which may not be initialized, so make sure it is.

Joe Perches fixes the use of the local macro XSTRINGIFY() to use
__stringify() instead.

Avinash corrects the mutex usage in client_subtask().  Fixed the RDMA
client to open again after reset since it is closed during a PF reset.

Jeff (me) clean up whitespace issues, where indentation was done
inconsistently and with spaces versus tabs.
