Thanks. Your new version in 2.3.45pre works correctly (shows me once
more why I'm not a kernel developer: I replaced all 3 occurrences of
dev_kfree_skb by if (in_irq()) ... else ..., which worked, too; you
replaced just one of them by dev_kfree_skb_irq; I had tried this before,
but always got the wrong one :-( ).
