I move that:
The TC agrees to resolve the following specification issue:
VIRTIO-132: ccw: handling of more than 64 virtqueues
--------------------------------------
For virtio-ccw devices using classic queue indicators, we cannot handle devices with more than 64 queues as the indicator value is a 64 bit integer and we would not be able to notify for the higher number virtqueues. The driver needs to use two-stage indicators if a device has more than 64 virtqueues.
--------------------------------------

The TC accepts the following proposed changes to the specification:
--------------------------------------
Make setting up classic queue indicators fail if the device has been configured for more than 64 virtqueues.

Proposed patch: https://www.oasis-open.org/apps/org/workgroup/virtio/email/archives/201702/msg00005.html
--------------------------------------

The TC agrees to include the above change(s) in specification version(s) "virtio 1.1 cs01", and future versions of the
specification.

Reminder: A Voting Member must be active in a TC to maintain voting rights.  As
the Virtio TC has adopted a standing rule to conduct business only by
electronic ballot, without Meetings, a Voting Member who fails to cast a ballot
in two consecutive Work Product Ballots loses his or her voting rights at the
close of the second ballot missed.
