I see NAPI poll routine might be called with interrupt disabled. Many (all?) NAPI drivers call netif_receive_skb() from its poll routine (as described in NAPI-HOWTO.txt), but I thought netif_receive_skb() cannot be called from irq context or irq disabled. So it seems the problem is not solved completely. Or am I missing something? --- Atsushi Nemoto - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
