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

88/*
89 * I have defined a new structure that can handle an NFS Version 3 file handle
90 * but the kernel still expects the old Version 2 one to be provided. The
91 * changes required in nfs_vfsops.c for using the new are documented there in
92 * comments. (I felt that breaking network booting code by changing this
93 * structure would not be prudent at this time, since almost all servers are
94 * still Version 2 anyhow.)
