Hello,
We are trying to port a network driver from 2.2.x to 2.4.x and have some

so we learned (the hard way ;-) that when running the

devinet.c(775):inetdev_event" in 2.4.x ?
the thing is I need to prevent Tx/Rx when a topology change is initiated
from the ioctl (registering a virtual adapter is just one example), so they
all share a single lock and I must use spin_lock_bh from
completing the operation when I use unregister_netdevice ?
does module_exit run inside rtnl_lock too ?

Now, the high

put a pointer to any of your data, including the most complex structure
you might envision, in that area. This allows you to pass anything

According to http://www.kernel.org, the latest stable kernel version is

In order to get a full 2.4.3-pre8 kernel do I have to:
