Merge branch 'mlxsw-ipv6-underlay'
Ido Schimmel says:
====================
mlxsw: Add support for VxLAN with IPv6 underlay
So far, mlxsw only supported VxLAN with IPv4 underlay. This patchset
extends mlxsw to also support VxLAN with IPv6 underlay. The main
difference is related to the way IPv6 addresses are handled by the
device. See patch #1 for a detailed explanation.
Patch #1 creates a common hash table to store the mapping from IPv6
addresses to KVDL indexes. This table is useful for both IP-in-IP and
VxLAN tunnels with an IPv6 underlay.
Patch #2 converts the IP-in-IP code to use the new hash table.
Patches #3-#6 are preparations.
Patch #7 finally adds support for VxLAN with IPv6 underlay.
Patch #8 removes a test case that checked that VxLAN configurations with
IPv6 underlay are vetoed by the driver.
A follow-up patchset will add forwarding selftests.
