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