Merge branch 'mlxsw-Reflect-nexthop-status-changes'
Jiri Pirko says: ==================== mlxsw: Reflect nexthop status changes Ido says: When the kernel forwards IPv4 packets via multipath routes it doesn't consider nexthops that are dead or linkdown. For example, if the nexthop netdev is administratively down or doesn't have a carrier. Devices capable of offloading such multipath routes need to be made aware of changes in the reflected nexthops' status. Otherwise, the device might forward packets via non-functional nexthops, resulting in packet loss. This patchset aims to fix that. The first 11 patches deal with the necessary restructuring in the mlxsw driver, so that it's able to correctly add and remove nexthops from the device's adjacency table. The 12th patch adds the NH_{ADD,DEL} events to the FIB notification chain. These notifications are sent whenever the kernel decides to add or remove a nexthop from the forwarding plane. Finally, the last three patches add support for these events in the mlxsw driver, which is currently the only driver capable of offloading multipath routes. ==================== Signed-off-by: David S.
