Actually, the soft interrupt stuff wouldn't have anything to do
with this. Those messages are a direct result of Tx DMA FIFO
underruns, which is directly related to the (visible to the Tulip)
throughput of the PCI bus, and not related at all to the speed
at which Tulip hardware interrupts are handled.
