42 * Structure that must be initialized for a diskless nfs client.
43 * This structure is used by nfs_mountroot() to set up the root and swap
44 * vnodes plus do a partial ifconfig(8) and route(8) so that the critical
45 * net interface can communicate with the server.
46 * Whether or not the swap area is nfs mounted is determined
47 * by the value in swdevt[0]. (equal to NODEV --> swap over nfs)
48 * Currently only works for AF_INET protocols.
49 * NB: All fields are stored in net byte order to avoid hassles with
50 * client/server byte ordering differences.
