Change ip6_route_multipath_add to send one notifciation with the full
route encoded with RTA_MULTIPATH instead of a series of individual routes.
This is done by adding a skip_notify flag to the nl_info struct. The
flag is used to skip sending of the notification in the fib code that
actually inserts the route. Once the full route has been added, a
notification is generated with all nexthops.
ip6_route_multipath_add handles 3 use cases: new routes, route replace,
and route append. The multipath notification generated needs to be
consistent with the order of the nexthops and it should be consistent
with the order in a FIB dump which means the route with the first nexthop
needs to be used as the route reference. For the first 2 cases (new and
replace), a reference to the route used to send the notification is
obtained by saving the first route added. For the append case, the last
route added is used to loop back to its first sibling route which is
the first nexthop in the multipath route.

IPv6 returns multipath routes as a series of individual routes making
their display and handling by userspace different and more complicated
than IPv4, putting the burden on the user to see that a route is part of
a multipath route and internally creating a multipath route if desired
(e.g., libnl does this as of commit 29b71371e764). This patch addresses
this difference, allowing multipath routes to be returned using the
RTA_MULTIPATH attribute.
The end result is that IPv6 multipath routes can be treated and displayed
in a format similar to IPv4:
$ ip -6 ro ls vrf red
2001:db8:1::/120 dev eth1 proto kernel metric 256 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium
2001:db8:200::/120 metric 1024
nexthop via 2001:db8:1::2 dev eth1 weight 1
nexthop via 2001:db8:2::2 dev eth2 weight 1

IPv4 allows multipath routes to be deleted using just the prefix and
length. For example:
$ ip ro ls vrf red
unreachable default metric 8192
1.1.1.0/24
nexthop via 10.100.1.254 dev eth1 weight 1
nexthop via 10.11.200.2 dev eth11.200 weight 1
10.11.200.0/24 dev eth11.200 proto kernel scope link src 10.11.200.3
10.100.1.0/24 dev eth1 proto kernel scope link src 10.100.1.3
$ ip ro del 1.1.1.0/24 vrf red
$ ip ro ls vrf red
unreachable default metric 8192
10.11.200.0/24 dev eth11.200 proto kernel scope link src 10.11.200.3
10.100.1.0/24 dev eth1 proto kernel scope link src 10.100.1.3
The same notation does not work with IPv6 because of how multipath routes
are implemented for IPv6. For IPv6 only the first nexthop of a multipath
route is deleted if the request contains only a prefix and length. This
leads to unnecessary complexity in userspace dealing with IPv6 multipath
routes.
This patch allows all nexthops to be deleted without specifying each one
in the delete request. Internally, this is done by walking the sibling
list of the route matching the specifications given (prefix, length,
metric, protocol, etc).
$ ip -6 ro ls vrf red
2001:db8:1::/120 dev eth1 proto kernel metric 256 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium
2001:db8:200::/120 via 2001:db8:1::2 dev eth1 metric 1024 pref medium
2001:db8:200::/120 via 2001:db8:2::2 dev eth2 metric 1024 pref medium
...
$ ip -6 ro del vrf red 2001:db8:200::/120
$ ip -6 ro ls vrf red
2001:db8:1::/120 dev eth1 proto kernel metric 256 pref medium
2001:db8:2::/120 dev eth2 proto kernel metric 256 pref medium
...
Because IPv6 allows individual nexthops to be deleted without deleting
the entire route, the ip6_route_multipath_del and non-multipath code
path (ip6_route_del) have to be discriminated so that all nexthops are
only deleted for the latter case. This is done by making the existing
fc_type in fib6_config a u16 and then adding a new u16 field with
fc_delete_all_nh as the first bit.

Since commit 364b6055738b ("net: busy-poll: return busypolling status to
drivers"), napi_complete_done() returns a boolean that can be used
by drivers to conditionally rearm interrupts.
This patch changes virtio_net to use this boolean to avoid a bit of
overhead for busy-poll users.
Jason reports about 1.1% improvement for 1 byte TCP_RR (burst 100).
