## Usage

The basic usage is: `adqsetup [options] <command> [parameters ...]`  

### Commands
- **help**: _Show help message_
- **examples**: _Creates an 'examples' subdirectory containing a set of 
example config files in the current directory._
- **apply**: _Apply a config file_
  - **[filename]**: (string) _Filename (relative or full path). If empty 
  or '-', read config file from stdin._
- **create**: _Create a 'quick-config' consisting of one traffic class._
  - **[name]**: (string) _User-defined name of traffic class. 
  'globals' and 'default' names are reserved and not allowed._
  - **[key]** **[value]**: (string, string) _One or more space-seperated 
  key and value pairs. See the above Class Configuration Parameter list for 
  possible keys and values._
- **reset**: _Remove ADQ traffic classes and filters. Does not reset any
global options._
- **persist**: _Persists a config file across reboots using a systemd 
service unit. One config per network interface, new configs overwrite old ones._
  - **[filename]**: (string) _Filename (relative or full path). If empty 
  or '-', read config file from stdin._
- **install**: _Installs the adqsetup script as a system-wide command 
on the PATH._

Global configuration parameters can be specified with the matching 
`--<key> <value>` command line option, and when using the `create` 
command class configuration parameters are specified with one or more 
`<key> <value>` pairs after the user-defined class name.


## Sample Usage

    adqsetup help
    adqsetup examples

    adqsetup apply memcached.conf
    adqsetup --dev=eth4 apply nginx.conf
    adqsetup --dev=eth3 persist eth3.conf

    cat memcached.conf | adqsetup apply

    adqsetup --dev=eth4 --priority=skbedit create myapp \
        queues 8 ports 11211
    adqsetup --dev=eth4 --priority=skbedit create myapp mode shared \
        queues 8 ports 11211-11218


## Sample Usage With Pipes From Bash Script

    #!/bin/bash 
    QUEUES=8
    # this will loop through a range
    # of busy_poll values
    for BP in {10000..50000..5000}; do 
    adqsetup --dev=eth4 apply <<EOF
        [globals]
        busypoll=$BP
        [nginx]
        queues=$QUEUES
        ports=80
    EOF
    # run test here
    done

## Notes

To load/use the different device drivers while creating the ADQ setup, --reload must be called along with --drivers parameter in the syntax. Device driver path is the full path to the .ko file (ex: ice-1.9.x/src/ice.ko).

The independent **pollers** argument passed to this tool doesn’t map directly to the **qps_per_poller** arguments passed to the driver. The ADQ Setup Tool allows the user to specify how many pollers for a particular TC instead of having to specify qps_per_poller.

## Common Issues

If you get a `/usr/bin/env: ‘python’: No such file or directory` error 
when you run the script, please install Python. If you have already installed 
Python, then try `whereis python` and you should see a message like: 
`python: /usr/bin/python2.7 /usr/bin/python3.6 /usr/bin/python3.6m /usr/bin/python3.9` 
on the first line of the output. Either run the version you wish to use 
manually: `python3.6 adqsetup.py help`, or create a 'python' symbolic 
link on the path: `ln -s /usr/bin/python3.6 /usr/local/bin/python`

When using the `pollers` feature, if your driver does **not** have 
independent poller support, you will see the following error:

    ** Setting independent poller **
    devlink answers: Invalid argument

## Other Issues

Please run the malfunctioning config with the command line `--debug` option, 
which should include a short stack trace at the end of the output. Send the 
configuration file (if used), full commmand line, and output to your Intel 
support contact.
