====================
40GbE Intel Wired LAN Driver Updates 2019-05-03

This series contains updates to the i40e driver only.

Carolyn changes the driver behavior to now disable the VF after one MDD
event instead of allowing a couple of MDD events before doing the reset.

Aleksandr changes the driver to only report an error when a VF tries to
remove VLAN when a port VLAN is configured, unless it is VLAN 0.  Also
extends the LLDP support to be able to keep the current LLDP state
persistent across a power cycle.

Maciej fixes the checksum calculation due to firmware changes, which
requires the driver to perform a double shadow RAM dump in some cases.

Adam adds advertising support for 40GBase_LR4, 40GBase_CR4 and fibre in
the driver.

Jake cleans up a check that is not needed and was producing a warning in
GCC 8.

Harshitha fixes a misleading message by ensuring that a success message
is only printed on the host side when the promiscuous mode change has
been successful.

Stefan Assmann adds the vendor id and device id to the dmesg log entry
during probe to help with bug reports when lspci output may not be
available.

Alice and Piotr add recovery mode support in the i40e driver, which is
needed for migrating from a structured to a flat firmware image.

v2: Removed patch 1 "i40e: replace switch-statement to speed-up
    retpoline-enabled builds" from the series since it is no longer
    needed.  Also updated the last patch in the series that introduces
    recovery mode support, to include a more detailed patch description
    and removed code not intended for the upstream kernel.
