Neutron error agreggation interfaces

[Carlos Augusto da Silva Martins]

Hello, I need to report a bug that consume cpu process a lot, its only a warning, but makes controller slowly.
Everybody that use link-aggregation to improve in netwrok troughtput, for example IFENSLAVE 2.6 or similar, have this issue below:

WARNING neutron.services.trunk.drivers.linuxbridge.agent.trunk_plumber [...] : Bad interface line: addrgenmode eui64 : IndexError: list index out of range

This occurs because the file (neutron/services/trunk/drivers/linuxbridge/agent/trunk_plumber.py) try to get interfaces name ("ip", "-d", "link", "list"), and If have an interface member of an aggregation, some additional lines is on output like this:

3: eno2: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 9000 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
    link/ether ... brd ff:ff:ff:ff:ff:ff promiscuity 1
    bond_slave state ACTIVE mii_status UP link_failure_count 0 perm_hwaddr ff:ab:12:ad:33:1a queue_id 0 ad_aggregator_id 3 ad_actor_oper_port_state 63
ad_partner_oper_port_state 61
addrgenmode eui64

Is possible a fix to this Warning, bypassing ifaces member of aggregations?

Thanks, we use Openstack Queens.

    Retrieve the device info in trunk_plumber using pyroute2

    IPWrapper.get_devices_info(), implemented using pyroute2, retrieves the
    device information including the VLAN tag and the parent name and index.

    This patch replaces Plumber._get_vlan_children() shell 'ip' commands in
    favor of this method.

This issue was fixed in the openstack/neutron 14.0.0.0b2 development milestone.

Looks like I'm also affected, but in Ocata.
This patch is not working there, due to:

AttributeError: 'module' object has no attribute 'get_devices_info'

Any chance for fix?
