Intel Wired LAN Driver Updates 2015-09-30

This series contains updates to i40e and i40evf only.

Vasily Averin provides a couple of rtnl lock/unlock fixes for both i40e
and i40evf.

Shannon provides several updates and fixes, first fixes up a type clash
in i40e_aq_rc_to_posix(), where the error codes are signed values, so we
need to treat them as such.  Then fixes up a padding issue where an
extra byte is added in i40e_aqc_get_cee_dcb_cfg_v1_resp to directly
acknowledge the padding.  Updated i40e to keep debugfs register read
and writes from accessing outside of the io-remapped space.  Added
support and device id for another 20 GbE device.

Jesse fixes the transmit hand workaround code for ARM that was causing
Tx hangs to still occur occasionally when there really was no hang.  Then
fixed the receive dropped counter to show up in netstat interface.
Refactor the interrupt enable function since it was always making the
caller add the base_vector from the VSI struct which is already passed
to the function.  Fix kbuild warnings found in 0day build infrastructure
by adding a harmless cast to a dev_info(), also fix 32 bit build
warnings found by sparse.

Greg fixed a configuration error that results if a port VLAN is set
for a VF before the VF driver is loaded, so that when the VF driver is
loaded the port VLAN is ignored.

Mitch fixes the use of QOS field consistently in
i40e_ndo_set_vf_port_vlan().  Modified the init timing of the driver
to increase stability on load/unload and SR-IOV enable/disable cycles.

Anjali updates i40e to not collect VEB stats if they are disabled in the
hardware for performance reasons.
