Description Jiri Pirko 2015-03-27 09:07:31 UTC

Description of problem:
When released from bridge, team device is removed from the system. That should not happen.

Version-Release number of selected component (if applicable):
teamd-1.15-1.el7.x86_64
but upstream (teamd-1.16) has the same problem

How reproducible:
always

Steps to Reproduce:
[root@rhel7 ~]# teamd -d -t teamx
[root@rhel7 ~]# ip l |grep teamx
8: teamx: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT 
[root@rhel7 ~]# ip link add brx type bridge
[root@rhel7 ~]# ip link set teamx master brx
[root@rhel7 ~]# ip link set teamx nomaster
[root@rhel7 ~]# ip l |grep teamx

Actual results:
teamx is no longer present

Expected results:
8: teamx: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT
teamx is present

Additional info:
If teamd is run with -N option and killed before teamx is removed from the bridge, teamx is not removed. That indicates that problem is in teamd.
