Well... - rtl8169_interrupt() acks all events before rtl8169_tx_interrupt() is called - the count of descriptors handled in rtl8169_tx_interrupt() is only limited by the number of packets submitted for TX at the time rtl8169_tx_interrupt() is called
-> if there is a stream of Tx events, it is possible that Tx descriptors are processed before the relevant event is notified to the host by the network adapter.
