37 * Structure holds parameters needed by nfs_mountroot(),
38 * which are filled in by nfs_boot_init() using either
39 * BOOTP (RFC951, RFC1048) or Sun RPC/bootparams.  These
40 * parameters are INET specific because nfs_boot_init()
41 * currently supports only AF_INET protocols.
42 *
43 * NB: All fields are stored in net byte order to avoid hassles
44 * with client/server byte ordering differences.
