The API is the same, but I did not see a path that would take a multipath route and update the dead nexthops when an interface is taken down with switchdev or rocker today. I could be wrong (and I will test again), but create a multipath route with nexthops on swp1 and swp2 and then call 'ip link set swp1 down' and let me know if you see rocker's ECMP routes get updated so only the nexthop on swp2 will be used. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
