Earlier the firmware was configuring single lossy COS profiles for Tx. But now more than one profiles is possible. Identify the profile a NIC driver should use based on the profile type hint provided in queue_cfg_info.
If the firmware does not set the bit to use profile type,
then we will use the older method to pick the COS queue for Tx.
