Address family only- CLI

A new parameter of afamilyOnly(true | false) can be set through the setupNetConfig which indicates whether you require only the afamily interfaces to be used. Example as below,

curl http://localhost:9000/node/controller/setupNetConfig -u Administrator:asdasd -d 'afamilyOnly=true&afamily=ipv4’ 

Corresponding changes need to be made to couchbase-cli. 

It would be clear to modify ip-family command (instead of adding new command for address_family_only) as below. 
Now it is: 

ip-family {--get | --set {--ipv4|--ipv6}}

change it to be:

ip-family {--get | --set {--ipv4|--ipv4only|--ipv6|-ipv6only}} 

The curl example above would be for "--ipv4only" option
