The underlying problem has to do with disabled irq. netif_receive_skb assumes irq to be enabled. Current via-velocity poll() method should narrow its (spinlocked) irq disabled section. What I've done should not require much analysis (aka "what could race with the rx bh processing in a napi driver ?") and avoids a more intrusive lockless napi design. -- Ueimor -- 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/
