Hi All,
  I have similar request for 
1) I cloned "/dev/tap/ and gone tap0 created. Now how to rename tap0 to other name or add a link with other name?
2) I used command " ifconfig tap0 link 96:9f:b5:4a:3d:4c active" to associate this new MAC address and make it as active
 this MAC address and old one as in active.I searched in net for code logic, but not able to find useful info.
How to achieve this via code?
3)  I used  command "dhcp.client -i tap0" for configuring IP address. 
How to achieve this via code?
4) Do we have any IOCTL commands sample code or any other way via code for the above requests?

Please help in achieving this
