Re: [PATCH iproute2-next v4 0/6] ip: nexthop: Support resilient groups

Support for resilient next-hop groups was recently accepted to Linux
kernel[1]. Resilient next-hop groups add a layer of indirection between the
SKB hash and the next hop. Thus the hash is used to reference a hash table
bucket, which is then used to reference a particular next hop. This allows
the system more flexibility when assigning SKB hash space to next hops.
Previously, each next hop had to be assigned a continuous range of SKB hash
space. With a hash table as an intermediate layer, it is possible to
reassign next hops with a hash table bucket granularity. In turn, this
mends issues with traffic flow redirection resulting from next hop removal
or adjustments in next-hop weights.

In this patch set, introduce support for resilient next-hop groups to
iproute2.

applied to iproute2-next. Thanks,
