wakeup on lan enable without compiling as module

wakeup on lan enable without compiling as module

[Thomas Glanzmann]

Hello,
I would like to build the 3c59x vortex module into the kernel (not as
module) but don't loose the ability to use wakeup-on-lan. Because it
seems to be impossible to specify 'module parameters' to a built-in
kernel module I tried the following patch, which doesn't work for me.
Could someone enlighten me how I can get the expected behaviour?

Thanks,
	Thomas

Hello again,
I have a few other problems with 2.6.13 (and also 2.6.12.5). When I pull
the ethernet plug from my card when the net is configured out and put it
back in, I have connectivity for about two till three seconds and after
that the card doesn't handle any more traffic. It did not happen with
the kernel I had before 2.6.12.5, but I don't remember the version.

0000:00:0c.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74)

Also I would like to know how can I put the card in wake-up-on-lan modus
when I use Magic Sysrq - O to turn it off.

Thanks,
	Thomas

Use
	3c59x.enable_wol on command line to pass parameters even if
	builtin.

The current practice is to use ethtool instead of module parameters to
do this. This driver doesn't support wake on lan settings via ethtool,
that would be the right way to fix.

I just got a private eMail with the solution. You can provide module
parameters using the following syntax:

	3c59x.enable_wol=1

and it works as expected.

IIRC you can pass "module parameters" to code built into the kernel on the
kernel command line.  I /think/ the form is
${module_name}_${module_arg}=....

So no need to modify the code.

                . here instead of _

It's documented in Documentation/kernel-parameters.txt .
