3.0 2723

v6 flows are getting stuck in hold state and all icmp echo requests are dropped. happening every single time.

root@csol2-node15:~# flow -l | grep :H -B2
   108644 2001:db8:0:f101::1:129 58 (5)
                         fd67::3:2231
(Gen: 5, K(nh):25, Action:H, Flags:, S(nh):0, Stats:27/4482, SPort 0)

Topology:

VM_Left(fd66::3)-------SC-------(fd67::3)VM_Right

VM_right is pinging a v6 address that is configured on a loopback interface of VM_left (and advertised via BGP to CN; BGPaaS config).

This is a regression; used to work in a couple builds earlier.
