Hi,

I am trying to get and set the Hardware address of the interface using
ioctl.
I am using the request SIOCGIFADDR/ SIOCSIFADDR

Using SIOCGIFADDR , errno is set to EADDRNOTAVAIL.
Using SIOCSIFADDR , errno is set to ESRCH.

what could be the reason for this.  any clues as where i am wrong.

Thanks in advance
Rajnish
