The purpose of this doc is about the config profile statements. Json
doesn't support comments. List all the example config files along with
profile descriptions.

1. os_profile.conf
    Recommended dsa config for OS usage such as page zeroing,compaction etc.
    - 1 group
            - 1 SWQ@16qd/1eng
            - max xfer size=2MB, max batch sz=32, bof=0
            - priority 10
            - threshold 15

2. app_profile.conf
    Recommended dsa default application profile.
    - 2 groups
            - Grp1 - SWQ1@8qd, 1eng
              max xfer size=16KB, max batch sz=32, bof=0, threshold=6
            - Grp2 - SWQ2@32qd, 1eng
              max xfer size=2MB, max batch sz=32, bof=0, threshold=28
            - Use group1 for smaller size ops with better latency characteristics

3. net_profile.conf
    Recommended dsa network accel profile
    - 4 groups, each with 1 DWQ@32qd/1 eng per group
            - Each DWQ has max xfer size=16KB
	    - DWQ threshold default 0

4. storage_profile.conf
    Recommended dsa storage accel profile
    - 2 groups each with 1 DWQ@32qd/1 eng per group
            - DWQ1 - max xfer size=16KB, max batch sz=32, bof=0
              for lower latency or synchronous ops
            - DWQ2 - max xfer size=2MB, max batch sz=32, bof=0
              for throughput ops
            - targeting SPDK-like uses
	    - DWQ threshold default 0

5. user_default_profile.conf
    Recommended dsa and iax accel profile template
    - The template specifies one DSA device and one IAX device
    - The attributes are applied to all WQs and engines on DSA and IAX
    - Run "accel-config config-user-default -c user_default_profile.conf"
      to load the config to all WQs and engines on all available DSA and
      IAX devices
    - The attributes can be edited. Two devices can be tailored to one device.
    - 1 group with all available WQs/all engs per group
            - Attributes that can be changed:
              "group_id":0
              "priority":10
              "block_on_fault":1
              "ats_disable":0
              "prs_disable":1
              "name":"user_default_wq"
            - Calcuated attributes:
              "size": max WQ size / max WQs
              "threshold": WQ size
            - Fixed attributes:
              "type": "user"
              "mode":"shared"
              "driver_name":"user",
            - Attributes with default values set by driver:
              "max_batch_size": default value
              "max_transfer_size": default value
              "op_config": default value
