[PATCH] iseries_veth: Supress spurious WARN_ON() at module unload
My patch from a few weeks back (now in mainline), called "Cleanup skbs to prevent unregister_netdevice() hanging", can cause our TX timeout code to fire on machines with lots of VLANs (because it takes > 2 seconds between when we stop the queues and when we're finished stopping the connections). When that happens the TX timeout code freaks out and does a WARN_ON() because as far as it's concerned there shouldn't be a TX timeout happening, which is fair enough. I have a "proper" fix for this, which is to a) do refcounting on connections and b) implement a proper ack timer so we don't keep unacked skbs lying around for ever. But for 2.6.12 I propose just supressing the WARN_ON(). Users will still see the "NETDEV WATCHDOG" warning, but that's not nearly as bad as a WARN_ON() which users interpret as an Oops.
