====================
net: vrf: Handle ipv6 multicast and link-local addresses
IPv6 multicast and link-local addresses require special handling by the
VRF driver. Rather than using the VRF device index and full FIB lookups,
packets to/from these addresses should use direct FIB lookups based on
the VRF device table.
Multicast routes do not make sense for the L3 master device directly.
Accordingly, do not add mcast routes for the device, and the VRF driver
should fail attempts to send packets to ipv6 mcast addresses on the
device (e.g, ping6 ff02::1%<vrf> should fail)
With this change connections into and out of a VRF enslaved device work
for multicast and link-local addresses (icmp, tcp, and udp). e.g.,
1. packets into VM with VRF config:
ping6 -c3 fe80::e0:f9ff:fe1c:b974%br1
ping6 -c3 ff02::1%br1
ssh -6 fe80::e0:f9ff:fe1c:b974%br1
2. packets going out a VRF enslaved device:
ping6 -c3 fe80::18f8:83ff:fe4b:7a2e%eth1
ping6 -c3 ff02::1%eth1
ssh -6 root@fe80::18f8:83ff:fe4b:7a2e%eth1
