* Scan all of our "ports" (Virtual Interfaces) looking for
Add 40G support for cxgb4vf driver. ethtool speed values are just numbers of megabits and there is no SPEED_40000 in ethtool speed values. To be consistent, use integer constants directly for all speeds. Use is_x_10g_port()("is 10Gb/s or higher") in cfg_queues() instead of is_10g_port() ("is exactly 10Gb/s"). Else we will end up using a single "Queue Set" on 40Gb/s adapters.
