* Description:
* Return the socket interface associated with this address family.

* Input Parameters:
* family - Socket address family
* type - Socket type
* protocol - Socket protocol
*
* Returned Value:
* On success, a non-NULL instance of struct sock_intf_s is returned. NULL
* is returned only if the address family is not supported.
