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