Subject: [net-next 00/20][pull request] 100GbE Intel Wired LAN Driver Updates 2016-07-20

This series contains updates to fm10k only.

Ngai-Mint provides a fix to clear PCIE_GMBX bits to ensure the proper
functioning of the mailbox global interrupt after a data path reset.

Jake provides most of the patches in the series, starting with a early
return from fm10k_down() if we are already down to prevent conflict with
other threads.  Fixed an issue where fm10k_update_stats() could cause
a null pointer dereference, specifically if it is called when we are going
down and the rings have been removed.  Cleans up and fixes the data path
reset flow, Tx hang routine and stop_hw().  Re-worked the fm10k_reinit()
to be more maintainable and fixed several inconsistencies with the work
flow.  Implemented fm10k_prepare_suspend() and fm10k_handle_resume()
which abstract around the now existing fm10k_prepare_for_reset and
fm10k_handle_reset. The new functions also handle stopping the service
task, which is something that the original re-init flow does not need.
Fixed an issue where if an FLR occurs, VF devices will be knocked out of
bus master mode, and the driver will be unable to recover from the reset
properly, so ensure bus master is enabled after every reset.  Fixed an
issue where a reset will occur as if for no reason, regularly every few
minutes until the switch manager software is loaded, which is caused
by continuously requesting the lport map so only do the request after
we have verified the switch mailbox is tx_ready.

The following are changes since commit c0d661ca3701f38d9313ca3954e3741ad92e3aaa:
  Merge branch 'mlxsw-per-prio-tc-counters'
and are available in the git repository at:
