[...] When MSI-X is enabled, a 'channel' is an MSI-X vector and the associated queues, i.e. total number of channels reported should be the total number of MSI-X vectors in use. (That was my intended interpretation, anyway. It may be that there is too much variation in the way queues and interrupts are associated for these operations to be defined in a general way.)
