* 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.
* 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.
