tg3 set_pauseframe() crash : some reproducibility

After crashing some more machines, I got a better understanding of how
to reproduce the tg3.ko kernel segfault reported a few minutes ago.
Sorry for sending two messages for this. I also discovered the command
"reboot -f", which is great :-)

I was wrong when comparing kernel versions: it finally seems to me
that they do not matter. The key factor is apparently

 "ifconfig up|down"

When the interface is down, the tg3 module being freshly loaded, then
any ethtool -A eth1 whatever does segfaults (in kernel).
If the interface is up, then it rolls.

Cheers,

Marc.

though. Just like the good old Usenet actually, only less convenient.
