Wrong type was used in ioctl definition.

However, this does not fix my dhcp problem:

I may have found the error, in  target_to_host_sockaddr() we only have
sa_family = tswap16(target_saddr->sa_family); w.r.t endian.
However a AF_INET also have:
    stSockAddr.sin_port = htons(1100);
    stSockAddr.sin_addr.s_addr = htonl(INADDR_ANY);
There is no endian conversion for these(there may be other cases too?)

That was premature but there is PF_PACKET/AF_PACKET:
struct sockaddr_ll {
               unsigned short sll_family;   /* Always AF_PACKET */
               unsigned short sll_protocol; /* Physical layer protocol */
               int            sll_ifindex;  /* Interface number */
               unsigned short sll_hatype;   /* ARP hardware type */
               unsigned char  sll_pkttype;  /* Packet type */
               unsigned char  sll_halen;    /* Length of address */
               unsigned char  sll_addr[8];  /* Physical layer address */
           };

BINDTODEVICE seems unimpl. too?

Both are used by busybox dhcp.
