[Bug 1989391] [NEW] Allowed Address Pairs which is netmask doesn't work

 

Public bug reported:

I have an environment ovn==21.03

I set one port's allowed address pairs is 192.168.1.12/24, I found only
ip=192.168.1.12 traffic can pass through, other ip eg:192.168.1.11 can
not. if I set allowed address pairs is 192.168.1.0/24, ip=192.168.1.11
traffic can pass through.

I looked at the code of ovn: https://github.com/ovn-
org/ovn/blob/98bac97c656c720780fae9b1e4c700eb13c36c29/northd/ovn-
northd.c#L4333

I think we should convert it and send it to ovn.
