Hi Joseph,
we also expect to have those commits in xenial.
The test fails with the patched kernel, only IFLA_NEW_NETNSID seems
there.
With the head of the iproute2 (patches to display those attributes have
been merged this week-end):
root@ubuntu1604:~# ./iproute2/ip/ip monitor link&
[1] 859
root@ubuntu1604:~# ip netns add foo
root@ubuntu1604:~# ip l a type dummy
root@ubuntu1604:~# 3: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN
group default
link/ether 5e:cb:ae:4a:69:f8 brd ff:ff:ff:ff:ff:ff
4: dummy1: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default
link/ether 06:de:2b:94:20:78 brd ff:ff:ff:ff:ff:ff
root@ubuntu1604:~# ip l s dummy1 netns foo
Deleted 4: dummy1: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group
default
link/ether 06:de:2b:94:20:78 brd ff:ff:ff:ff:ff:ff new-nsid 0
=> only new-nsid is displayed.
With an upstream kernel, you have:
Deleted 5: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group
default
link/ether 72:33:30:ba:4c:eb brd ff:ff:ff:ff:ff:ff new-nsid 0 new-ifindex 5
'new-ifindex' is also displayed
