During the watchdog the e100 driver reads all of the status registers from the actual hardware. There are 26 (worst case) register reads. There is also a spin lock for another check in the watchdog. It would still surprise me that all of this would take 500 usec. If you are seeing this delay, you can comment out the scheduling of the watchdog to see if this goes away. We'll need to narrow down exactly what in the watchdog is causing the delay
