 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.
