ipv4: fib: Provide per-nexthop offload indication
Ido says:
Offload indication for IPv4 routes is currently set in the FIB info's
flags. When multipath routes are employed, this can lead to a route being
marked as offloaded although only one of its nexthops is actually
offloaded.
Instead, this patchset aims to proivde a higher resolution for the offload
indication and report it on a per-nexthop basis.
Example output from patched iproute:
$ ip route show 192.168.200.0/24
192.168.200.0/24
nexthop via 192.168.100.2 dev enp3s0np7 weight 1 offload
nexthop via 192.168.101.3 dev enp3s0np8 weight 1
And once the second gateway is resolved:
$ ip route show 192.168.200.0/24
192.168.200.0/24
nexthop via 192.168.100.2 dev enp3s0np7 weight 1 offload
nexthop via 192.168.101.3 dev enp3s0np8 weight 1 offload
First patch teaches the kernel to look for the offload indication in the
nexthop flags. Patches 2-5 adjust current capable drivers to provide
offload indication on a per-nexthop basis. Last patch removes no longer
used functions to set offload indication in the FIB info's flags.
