Subject: [PATCH net-next v2 1/9] ice: count combined queues using Rx/Tx count

From: Michal Swiatkowski <michal.swiatkowski@...ux.intel.com>

Previous implementation assumes that there is 1:1 matching between
vectors and queues. It isn't always true.

Get minimum value from Rx/Tx queues to determine combined queues number.
