Merge branch 'mlxsw-IPv6-and-reference-counting-fixes'
Ido Schimmel says:
====================
mlxsw: IPv6 and reference counting fixes
The first three patches fix a mismatch between the new IPv6 behavior
introduced in commit f34436a43092 ("net/ipv6: Simplify route replace and
appending into multipath route") and mlxsw. The patches allow the driver
to support multipathing in IPv6 overlays with GRE tunnel devices. A
selftest will be submitted when net-next opens.
The last patch fixes a reference count problem of the port_vlan struct.
I plan to simplify the code in net-next, so that reference counting is
not necessary anymore.
