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

86: * comments. (I felt that breaking network booting code by changing this
87: * structure would not be prudent at this time, since almost all servers are
