cleanup: 

-update comments
-remove remaining references to "bootparam"
-don't try to interpret extra arguments to net_open() - we
 get only passed a NULL anyway (see devopen.c)

* This module implements a "raw device" interface suitable for
* use by the stand-alone I/O library NFS code. This interface
* use by the stand-alone I/O library NFS and TFTP code. This interface
* 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.
* purpose of initializing the network interface and getting boot
* parameters.
*
* 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).
* find interface - netif_open()
* BOOTP for IP address - bootp()
