[Bug 1918702] [NEW] [OVN] BW limit QoS rules assigned to SR-IOV ports are created on NBDB

 

Public bug reported:

Description of problem:
When a QoS policy with an egress BW limit rule is assigned to a SR-IOV port (type direct or macvtap), the corresponding rule should be managed by the SR-IOV agent and should not be added to the OVN NBDB's QoS table.

However, the entry on the QoS table is created for that port, which is
wrong.

The rule is also applied to the dataplane traffic shaper, which is
correct.

Steps to Reproduce:
1) Create qos policy with an egress bw limit rule and assing it to an SRIOV port:
   # openstack network qos policy create p0
   # openstack network qos rule create p0 --type bandwidth-limit --max-kbps 500000000 \
     --max-burst-kbits 40000000
   # openstack port set --qos-policy p0 0917ed75-6362-4522-a468-c3a8c89712fd

2) Check qos ovn nbdb table
   # ovn-nbctl --db=tcp:10.20.1.73:6641 list qos | grep -C5 $qos_uuid

_uuid               : c2758e23-195e-4efa-8f9f-c057955ba6c3
action              : {}
bandwidth           : {burst=40000000, rate=540000}
direction           : from-lport
external_ids        : {}
match               : "inport == \"0917ed75-6362-4522-a468-c3a8c89712fd\""
priority            : 2002

This kind of testing is not available in the Opendev CI because there
are not SR-IOV environments.
