====================
40GbE Intel Wired LAN Driver Updates 2016-05-14

This series contains updates to i40e and i40evf.

Kevin adds support to disable link on all ports and changes bits set
for telling firmware the PHY needs to be modified by the driver.

Anjali adds a feature to enable/disable all multicast for a trusted
VF.  Added priv-flag knob to configure global true promiscuous
support.

Shannon adds the support code for calling the admin queue API call
aq_set_switch_config().

Mitch modifies the VF, to log a message if an untrusted VF attempts to
configure promiscuous mode, but lies to it and returns everything is ok
instead of returning an error.  Corrects the logic for reporting the
receive packet hash.  Fixed the adding of a broadcast filter for VFs,
since that all VSIs are configured to receive broadcasts as default,
so do not need to add a filter.

Catherine refactors the ethtool get_settings to report the possible
supported link modes from what we know about the current PHY type and
that with the firmware supported PHY types.

Jacob changes the driver to use WARN_ONCE in order to highlight the
issue, but do not display a warning every time when receive hang
message is received.

Akeem corrects receive ptype payload layer for non_tunneled IPv6, when
it should be layer 4 for UDP, instead of layer 3.

Dan Carpenter fixes an uninitialized variable bug.
