Subject[PATCH net-next v2 2/9] if_addr: add IFA_TARGET_NETNSID
Date
This adds a new IFA_TARGET_NETNSID property to be used by address
families such as PF_INET and PF_INET6.
The IFA_TARGET_NETNSID property can be used to send a network namespace
identifier as part of a request. If a IFA_TARGET_NETNSID property is
identified it will be used to retrieve the target network namespace in
which the request is to be made.

v1->v2:
- rename from IFA_IF_NETNSID to IFA_TARGET_NETNSID

v0->v1:
- unchanged
Note, I did not change the property name to IFA_TARGET_NSID as there
was no clear agreement what would be preferred. My personal preference
is to keep the IFA_IF_NETNSID name because it aligns naturally with
the IFLA_IF_NETNSID property for RTM_*LINK requests. Jiri seems to
prefer this name too.
However, if there is agreement that another property name makes more
sense I'm happy to send a v2 that changes this.
