Since I have not seen anyone answer your question, here is a little
function that should add an IP Alias (this works on the current

void addAlias(const char *pName, const char *pAddr, const char *pMask)
  struct ifaliasreq      aliasreq;
  struct sockaddr_in    *in;

  /* initialize alias request */
  memset(&aliasreq, 0, sizeof(aliasreq));
  sprintf(aliasreq.ifra_name, pName);

  /* initialize alias address */
  in = (struct sockaddr_in *)&aliasreq.ifra_addr;
  in->sin_family = AF_INET;
  in->sin_len    = sizeof(aliasreq.ifra_addr);
  in->sin_addr.s_addr = inet_addr(pAddr);

  /* initialize alias mask */
  in = (struct sockaddr_in *)&aliasreq.ifra_mask;
  in->sin_family = AF_INET;
  in->sin_len    = sizeof(aliasreq.ifra_mask);
  in->sin_addr.s_addr = inet_addr(pMask);

  /* call to setup the alias */
  rtems_bsdnet_ifconfig(pName, SIOCAIFADDR, &aliasreq);

Good Luck,
