Subject: [patch net-next 00/42] mlxsw: Implement IPV4 unicast routing
From: Jiri Pirko <jiri@...lanox.com>
This patchset enables IPv4 unicast routing in the Mellanox Spectrum ASIC
switch driver. The basic dependencies are already present in the kernel and
used by rocker.
Patches 1-3 add a couple of dependencies outside the driver. Namely, the
ability to propagate ndo_neigh_construct()/destroy() through stacked devices and
a notification whenever DELAY_PROBE_TIME changes. When propagated down, the
ndos allow drivers to add and remove neighbour entries from their private
neighbour table. The DELAY_PROBE_TIME notification gives drivers the ability to
correctly configure their polling interval for neighbour activity, so that
active neighbour won't be marked as STALE.
Patches 4-25 add missing infrastructure in the driver for the router,
initialize it and lay the groundwork for the introduction of router
interfaces. These are introduced in patches 26-29. At this point the router
still operates in slowpath, but that's needed in order not to introduce a
regression.
Patches 30-33 add the neighbour offloading infrastructure, where patch 33 uses
the DELAY_PROBE_TIME notification in order to correctly configure the device's
polling interval. Patch 34 finally programs neighbours to the device's table
based on NEIGH_UPDATE notifications, so that directly connected routes can
be used.
Patches 35-42 build upon the previous patches and extend the router with
remote routes (nexthop) support.
