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

83: * comments. (I felt that breaking network booting code by changing this
84: * structure would not be prudent at this time, since almost all servers are
85: * still Version 2 anyhow.)
