Benno Rice 3c463a49eb Switch to using a normal mutex instead of a spin mutex. ... We still use the interrupt filter due to performance problems that show up if we don't. The main problem seen is that, due to the interrupt being edge triggered, we occasionally miss interrupts which leads us to not notice that we can transmit more packets. Using the new approach, which just schedules a task on a taskqueue, we are guaranteed to have the task run even if the interrupt arrived while we were already executing. If we were to use an ithread the system would mask the interrupt while the handler is run and we'd miss interrupts.		2008-06-11 07:26:02 +00:00
