net_device: set_multicast_list called from interrupt?

net_device: set_multicast_list called from interrupt?

Hi there!

I don't know if this is the right place, but I hope so.

I wrote a network-driver years ago for the 2.4er kernel's.

Now I ported it to the 2.6er kernel but I get some problems because
set_multicast_list is called from an interrupt and my driver want's to
free/allocate some memory.

Why did the driver work under 2.4, and now stops running on 2.6?

I had a look at http://lwn.net/Articles/30107/:
Driver porting: Network drivers

but there was nothing about newly implemented soft-interrupts.

Thanks,
Martin

Ah, just tested it under 2.4er. It's called from an interrupt too.
So I have to workaround the free/alloc.

Sorry!
