The dhcp request field for hardware type is hardcoded to 1 (ethernet),
which may cause the server to ignore the requests on other media,
such as token ring. The correction is simple - use the if reported
family to set the hw type. The following patch has been tested to fix
the problem on a token ring net, without affecting ethernet operation.
