This patch implements the command handling mechanism. The digital stack serializes all commands sent to the driver. This means that the digital stack waits for the reply of the current command before sending a new one. So there is no command queue managed at driver level. All Port-100 commands are asynchronous. If the command has been sent successfully to the device, it replies with an ACK frame. Then the command response is received (or actually no-response in case of timeout or error) and a command complete work on the system workqueue is responsible for sending the response (or the error) back to the digital stack. The digital stack requires some commands to be synchronous, mainly hardware configuration ones. These commands use the asynchronous command path but are made synchronous by using a completion object.
