* This module implements a "raw device" interface suitable for

|

* does not support any "block" access, and exists only for the

* purpose of initializing the network interface, getting boot
|
||||
* parameters, and performing the NFS mount.
|

*
|

* At open time, this does:
|

*
|

* find interface - netif_open()
|
||||
* RARP for IP address - rarp_getipaddress()
|
||||
* RPC/bootparams - callrpc(d, RPC_BOOTPARAMS, ...)
|
||||
* RPC/mountd - nfs_mount(sock, ip, path)
|
||||
*
|
||||
* the root file handle from mountd is saved in a global
|
||||
* for use by the NFS open code (NFS/lookup).
