Subject: [PATCH net-next 2/5] if_addr: add IFA_IF_NETNSID

This adds a new IFA_IF_NETNSID property to be used by address families such
as PF_INET and PF_INET6.
The IFA_IF_NETNSID property can be used to send a network namespace
identifier as part of a request. If a IFA_IF_NETNSID property is identified
it will be used to retrieve the target network namespace in which the
request is to be made.
