Subject: [PATCH net-next 0/7] mlxsw: Add support for new multipath hash policies

From: Ido Schimmel <idosch@...dia.com>

This patchset adds support for two new multipath hash policies in mlxsw.

Patch #1 emits net events whenever the
net.ipv{4,6}.fib_multipath_hash_fields sysctls are changed. This allows
listeners to react to changes in the packet fields used for the
computation of the multipath hash.

Patches #2-#3 refactor the code in mlxsw that is responsible for the
configuration of the multipath hash, so that it will be easier to extend
for the two new policies.

Patch #4 adds the register fields required to support the new policies.

Patch #5-#7 add support for inner layer 3 and custom multipath hash
policies.

Tested using following forwarding selftests:

* custom_multipath_hash.sh
* gre_custom_multipath_hash.sh
* gre_inner_v4_multipath.sh
* gre_inner_v6_multipath.sh

Ido Schimmel (7):
  net: Add notifications when multipath hash field change
  mlxsw: spectrum_router: Replace if statement with a switch statement
  mlxsw: spectrum_router: Move multipath hash configuration to a bitmap
  mlxsw: reg: Add inner packet fields to RECRv2 register
  mlxsw: spectrum_outer: Factor out helper for common outer fields
  mlxsw: spectrum_router: Add support for inner layer 3 multipath hash
    policy
  mlxsw: spectrum_router: Add support for custom multipath hash policy
