[iwl-next,v5,00/10] Implement support for SRIOV + LAG

Message

Implement support for SRIOV VF's on interfaces that are in an
aggregate interface.

The first interface added into the aggregate will be flagged as
the primary interface, and this primary interface will be
responsible for managing the VF's resources.  VF's created on the
primary are the only VFs that will be supported on the aggregate.
Only Active-Backup mode will be supported and only aggregates whose
primary interface is in switchdev mode will be supported.

Additional restrictions on what interfaces can be added to the aggregate
and still support SRIOV VFs are:
- interfaces have to all be on the same physical NIC
- all interfaces have to have the same QoS settings
- interfaces have to have the FW LLDP agent disabled
- only the primary interface is to be put into switchdev mode
- no more than two interfaces in the aggregate

Changes since v1:
Fix typo in commit message
Fix typos in warning messages
Fix typo in function header
Use correct bitwise operator instead of boolean

Changes since v2:
Rebase on current next-queue
Fix typos in commits
Fix typos in function headers
use %u for unsigned values in debug message
Refactor common code in node moves to subfunction

Changes since v3:
Fix typos in warning messages
move refactor of common code to earlier patch
expand use of refactored code
move prototype and func call into patch that defines func

Changes since v4:
Change module_init to use goto unwind approach
Change function name to be more descriptive
chagen variable to be more scope specific
Make sure non-feature specific functions are still performed
Free correct memory
Fix typos in warning messages
added check for invalid TEID in queue cfg

Dave Ertman (9):
  ice: Add driver support for firmware changes for LAG
  ice: changes to the interface with the HW and FW for SRIOV_VF+LAG
  ice: implement lag netdev event handler
  ice: process events created by lag netdev event handler
  ice: Flesh out implementation of support for SRIOV on bonded interface
  ice: support non-standard teardown of bond interface
  ice: enforce interface eligibility and add messaging for SRIOV LAG
  ice: enforce no DCB config changing when in bond
  ice: update reset path for SRIOV LAG support

Jacob Keller (1):
  ice: Correctly initialize queue context values
