====================
mlxsw: Add support for nexthop objects

This patch set adds support for nexthop objects in mlxsw. Nexthop
objects are treated as another front-end for programming nexthops, in
addition to the existing IPv4 and IPv6 front-ends.

Patch #1 registers a listener to the nexthop notification chain and
parses the nexthop information into the existing mlxsw data structures
that are already used by the IPv4 and IPv6 front-ends. Blackhole
nexthops are currently rejected. Support will be added in a follow-up
patch set.

Patch #2 extends mlxsw to resolve its internal nexthop objects from the
nexthop identifier encoded in the FIB info of the notified routes.

Patch #3 finally removes the limitation of rejecting routes that use
nexthop objects.

Patch #4 adds a selftest.

Patches #5-#8 add generic forwarding selftests that can be used with
veth pairs or physical loopbacks.
