Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2019-11-08

Another series that contains updates to the ice driver only.

Anirudh cleans up the code of kernel config of ifdef wrappers by moving
code that is needed by DCB to disable and enable the PF VSI for
configuration.  Implements ice_vsi_type_str() to convert an VSI type
enum value to its string equivalent to help identify VSI types from
module print statements.

Usha and Tarun add support for setting the maximum per-queue bit rate
for transmit queues.

Dave implements dcb_nl set functions and supporting software DCB
functions to support the callbacks defined in the dcbnl_rtnl_ops
structure.

Henry adds a check to ensure we are not resetting the device when trying
to configure it, and to return -EBUSY during a reset.

Usha fixes a call trace caused by the receive/transmit descriptor size
change request via ethtool when DCB is configured by using the number of
enabled queues and not the total number of allocated queues.

Paul cleans up and refactors the software LLDP configuration to handle
when firmware DCBX is disabled.

Akeem adds checks to ensure the VF or PF is not disabled before honoring
mailbox messages to configure the VF.

Brett corrects the check to make sure the vector_id passed down from
iavf is less than the max allowed interrupts per VF.  Updates a flag bit
to align with the current specification.

Bruce updates a switch statement to use the correct status of the
Download Package AQ command.  Does some housekeeping by cleaning up a
conditional check that is not needed.

Mitch shortens up the delay for SQ responses to resolve issues with VF
resets failing.

Jake cleans up the code reducing namespace pollution and to simplify
ice_debug_cq() since it always uses the same mask, not need to pass it
in.  Improve debugging by adding the command opcode in the debug
messages that print an error code.

v2: fixed reverse christmas tree issue in patch 3 of the series.
