[Neutron][FFE] request for QoS policy update for bound ports feature

Hi,

I would like to ask for FFE for the RFE "allow replacing the QoS policy of bound port", [1]. This feature adds the extra step to port update operation to change the allocation in Placement to the min_kbps values of the new QoS policy, if the port has a QoS policy with minimum_bandwidth rule and is bound and used by a server.

In neutron there's one open patch: https://review.opendev.org/747774

There's an open bug report for the neutron-lib side: https://bugs.launchpad.net/neutron/+bug/1894825 (placement story: https://storyboard.openstack.org/#!/story/2008111 ) and a fix for that: https://review.opendev.org/750349

Thanks and Regards, Lajos Katona (lajoskatona)
