Which driver are you using?

Thanks, Hugh.

    I am trying to change the MAC address of a network interface using ioctl() api in my program, but it always returns 
error 103 (Operation not supported).
    
    I am able to change it through the shell using command "ifconfig eth1 link 00:50:56:2e:88:1a active". 
    I want to do the same using system APIs, but it gives error. Below is the code snippet, please suggest any other way
 to do the same
    
    struct ifaliasreq  addreq;
    memset(&addreq, 0, sizeof(addreq));
    strcpy(addreq.ifra_name, "eth1");
    addreq.ifra_addr.sa_family = AF_LINK;
    bcopy(mac, addreq.ifra_addr.sa_data, 6);
    ioctl(s, SIOCAIFADDR, &addreq);
