10.4 DPM DRIVER MANAGEMENT API

The dpm network driver management API is an api extension primarily used by the ‘dmUtil’ command line utility to enable various management functions or to acquire driver status and statistics. The typical api usage sequence is as follows:

1.User enters ‘dmUtil’ command and parameters as shown in the following example:

./dmUtil –s eth1

2.dmUtil parses command line and prepares an “ioctl” request block to send to driver. A pointer to a application buffer to hold the text message results (for example formatted statistics) is provided by dmUtil in the request block.

3.Driver receives ioctl request block performs action and copies result data to applications message buffer.

The following is an API description of the management ioctl commands issued to the driver from the ‘dmUtil’ application’s viewpoint:
