title: How to configure Network Interface in vxworks-cert-6.6 without using ifLib
body: <p>I am working on Kontron board with Vxworks-cert-6.6 RTOS in it. 
  My current goal is to bring-up the <strong>Network Interface</strong> in it, and set a static IP address and a netmask for that interface.</p>
  
  <p>As of now, I know 2 ways to achieve my requirement (to set a static IP address):</p>
  
  <ol>
  <li><p>by providing <strong>ead</strong> bootline parameter, specifying IP address and netmask for boot interface.</p></li>
  <li><p>by using ifLib network interface library.</p></li>
  </ol>
  
  <p>The first method I cannot opt for the reason, after deployment end-user cannot change every time the <strong>ead</strong> bootline parameter for IP address to set and compile the whole bootrom and deploy back the device.</p>
  
  <p>And, the second method is not permitted for me to use because for the reason, the Vxworks-cert package I am using doesn't come with ifLib library in it.</p>
  
  <p>So above said both the methods are not feasible in my case. Even I have thought of a 3rd method to change bootline parameter during runtime and reboot. But this method is also not feasible for the main reason, the Kontron board I am using doesn't support NVRAM, and hence the bootline parameter I have changed during runtime doesn't withstand power-off/on cycles and new desired IP address will not be set.</p>
  
  <p>Can anyone suggest me a method to achieve this; if any reference links it will be more helpful. Thank you in advance for all your helps.</p>
