The "Unsolicited Neighbor Advertisement" seems to be the
equivalent of GARP for IPv6.
http://tools.ietf.org/html/rfc2461#section-7.2.6
The problem motivating this fix was seen with IPv4 though.

High level comment earlier that still applies:
1) garp reply is still being used rather than garp request
garp replies are more likely to be dropped or explicitly filtered so
garp requests are "better"
Do you need to make changes to build_lswitch_flows() to allow the garp
requests out t

In some usecases such as VM migration or when VMs reuse IP addresses,
VMs become unreachable externally because
external switches/routers on localnet
have stale port-mac or arp caches. The problem resolves
after some time when the caches ageout which could be
minutes for port-mac bindings or hours
