[Bridge] [PATCH net-next 0/8] mlxsw: Add VxLAN support with VLAN-aware bridges

[Ido Schimmel <idosch@mellanox.com>]

Commit 53e50a6ec24d ("Merge branch 'mlxsw-Add-VxLAN-support'") added
mlxsw support for VxLAN when the VxLAN device was enslaved to
VLAN-unaware bridges. This patchset extends mlxsw to also support VxLAN
with VLAN-aware bridges.

With VLAN-aware bridges, the VxLAN device's VNI is mapped to the VLAN
that is configured as 'pvid untagged' on the corresponding bridge port.
To prevent ambiguity, mlxsw forbids configurations in which the same
VLAN is configured as 'pvid untagged' on multiple VxLAN devices.

Patches #1-#2 add the necessary APIs in mlxsw and the bridge driver.

Patches #3-#4 perform small refactoring in order to prepare mlxsw for
VLAN-aware support.

Patch #5 finally enables the enslavement of VxLAN devices to a
VLAN-aware bridge. Among other things, it extends mlxsw to handle
switchdev notifications about VLAN add / delete on a VxLAN device
enslaved to an offloaded VLAN-aware bridge.

Patches #6-#8 add selftests to test the new functionality.
