Add code to query and set the number of channels on the primary VSI for a PF. This is accessed from the 'ethtool -l' and 'ethtool -L' commands, respectively. Though the ice driver supports asymmetric queues report an IRQ vector that has both Rx and Tx queues attached and is counted as a 'combined' channel.
