Subject: [PATCH net-next 00/15] mlxsw: Offload IPv6 multicast routes

Yuval says:

The series is intended to allow offloading IPv6 multicast routes
and is split into two parts:

  - First half of the patches continue extending ip6mr [& refactor ipmr]
    with missing bits necessary for the offloading - fib-notifications,
    mfc refcounting and default rule identification.

  - Second half of the patches extend functionality inside mlxsw,
    beginning with extending lower-parts to support IPv6 mroutes
    to host and later extending the router/mr internal APIs within
    the driver to accommodate support in ipv6 configurations.
    Lastly it adds support in the RTNL_FAMILY_IP6MR notifications,
    allowing driver to react and offload related routes.

Yuval Mintz (15):
  ipmr: Make vif fib notifiers common
  ipmr: Make MFC fib notifiers common
  ipmr: Make ipmr_dump() common
  ip6mr: Support fib notifications
  ip6mr: Add API for default_rule fib
  ip6mr: Add refcounting to mfc
  mlxsw: reg: Configure RIF to forward IPv6 multicast packets
  mlxsw: reg: Add register settings for IPv6 multicast routing
  mlxsw: spectrum_mr: Pass protocol as part of catchall route params
  mlxsw: spectrum_router: Support IPv6 multicast to host CPU
  mlxsw: spectrum_mr: Convert into using mr_mfc
  mlxsw: spectrum_router: Make IPMR-related APIs family agnostic
  mlxsw: spectrum_mr: Add ipv6 specific operations
  mlxsw: spectrum_router: Process IP6MR fib notification
  mlxsw: spectrum: Add multicast router trap for PIMv6
