ipv6 rule created with a /32 causes host connectivity issues

When using IPv6 I lose connectivity on the host interface when adding an IPv6 address to a dataplane interface.
Running tcpdump shows ping requests inbound, but the reply is going out vpp1.
Looking at the ip rules, there is a rule with the source address of the dataplane interface and a /32 bitmask. I imagine this is meant to be a /128.
[root@tnsr ~]# ip -6 rule list 0: from all lookup local 1000: from all to fd00:0:0:1::105/64 lookup main 5000: from fd00:0:0:1::105/32 lookup 75 32766: from all lookup main
[root@tnsr ~]# ip -6 route show table 75 default via fe80::6 dev vpp1 metric 1024 pref medium
Thanks for bringing this to our attention. As we have been discussing over email, we have reproduced the issue and working on it.
