Subject: [PATCH net-next 00/10][pull request] ice: Implement support for SRIOV + LAG

Dave Ertman says:

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.

The ice-lag DDP must be loaded to support this feature.

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

The following are changes since commit 2303fae130640874823ea1bc7ec65c3cd074a7eb:
  net: skbuff: remove unused HAVE_HW_TIME_STAMP feature define
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE

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
