Application Information

The included application, called "rcc" (for RedCreek Control), is an 
example of a user-space application (i.e., not running within kernel
space).  It issues ioctl commands to communicate with the PCI driver.  
It is intended for reference only.  It can currently report any of 
the following information:

   - PCI driver information ("getinfo")
   - card statistics ("getstats")
   - card's ip address & netmask ("getipnmask")
   - card's mac address ("getmac")
   - current speed ("getspeed")
   - firmware version string ("getfirmware")
   - status of the link (up or down) ("getstatus")

This program needs to run as root, to avoid encountering permission 
problems.  An alternative is to change the permission and ownership
so that it runs as a setuid root process (for example, "chown 
root.root rcc; chmod u+s rcc").


Quick PCI driver background

The adapter has its own IP and mac addresses which you have to
assign using the RedCreek manager (assuming the adapter is
running 3.X firmware).  Your linux box will not know anything 
about the adapter's IP address -- ie, the adapter will show up 
as a regular nic.  You will assign the linux box IP address using 
the "ifconfig" command, as mentioned below.

To compile the driver, simply type "make".  
This, of course, assumes that you have GNU compiler environment
already setup on a linux box.  The .c and .h files were copied 
to a dos filesystem (the floppy), so you may have to use "dos2unix" to 
convert it back to a unix text file.  Keep in mind that the driver
currently works with kernels 2.0.X only.  Furthermore, it was only
tested with kernel 2.0.34.  There is work being done on porting the
driver to the 2.1.X kernel, however, it's still incomplete.

When the compile is done, you'll send up with three object files
related to the driver: rcmtl.o, rcpci45.o, and rc.o;  rcmtl.o
is the RedCreek API message layer; rcpci45.o is the upper level
Linux driver which contains the interface to the kernel.  Finally,
since the driver is compiled as a loadable module, rcmtl.o and
rcpci45.o are linked together into a third file, rc.o, which is the
actual driver.  

To load the driver:

"insmod rc"

If you are in console mode, you'll see a few messages send by the
driver.  One of the messages will indicated how many adapters were
found; the messages are also stored in /var/log/messages, so they
can be viewed later.  If you are running X, then you'll have to 
view the messages by examining /var/log/messages.

The adapter will show up as a regular nic.  Thus, if you have only
one nic (the pci card) in your box, you would at this point configure
it with the following commands:

mandatory:
"ifconfig eth0 <your linux box IP address (NOT the IP address of the 
                adapter!>"
"route add -net <your network address> eth0"

optional (if you want to be able to access other networks):
"route add default gw <your default gateway IP address> eth0"

Done.  Type "ifconfig" to see "eth0" and the packet count, as well
as the IP address, net mask, etc.

To unload the driver, you first have to shutdown the interface:

"ifconfig eth0 down"

Then you unload the driver with "rmmod rc".
