    net: Initial nexthop code · ab84be7e
    David Ahern authored
    Barebones start point for nexthops. Implementation for RTM commands,
    notifications, management of rbtree for holding nexthops by id, and
    kernel side data structures for nexthops and nexthop config.
    
    Nexthops are maintained in an rbtree sorted by id. Similar to routes,
    nexthops are configured per namespace using netns_nexthop struct added
    to struct net.
    
    Nexthop notifications are sent when a nexthop is added or deleted,
    but NOT if the delete is due to a device event or network namespace
    teardown (which also involves device events). Applications are
    expected to use the device down event to flush nexthops and any
    routes used by the nexthops.
