> Previous devices could only allocate 4 MSI-X vectors per VF so there was a
> limitation of 4 queues. 800-series hardware can allocate more than 4 MSI-X
> vectors, so expand the limitation on the number of queues that the driver
> can support to account for these capabilities.
> 
> Fix eththool channel operations to accommodate this change and adjust the
> reporting of max number of queues to what is given to us by the PF. Since
> we're not requesting queues above this value, just trigger reset to activate
> the queues, which we already own.
> 
> Finally, fix a test condition that would display an incorrect error message.
