This patch improves performance of the Tsi108 Ethernet driver by
changing interrupt handling for frame receive path. It reduces number of
interrupts generated for received frames and therefore lowers CPU
utilization by the device driver.

Sorry, I missed that you reduced the interval to 20 ms. Still, a bit on
the h

This patch improves performance of the Tsi108 Ethernet driver by
changing interrupt handling
for frame receive path. It reduces number of interrupts generated for
received frames and therefore lowers CPU utilization by the device
driver.
