Maksim Yevmenkin cd1fb2e095 Before it gets lost in the noise. ... Put a bandaid to prevent ixgbe(4) from completely locking up the system under high load. Our platform has a few CPU cores and a single active ixgbe(4) port with 4 queues. Under high enough traffic load, at about 7.5GBs and 700,000 packets/sec (outbound), the entire system would deadlock. What we found was that each CPU was in an endless loop on a different ix taskqueue thread. The OACTIVE flag had gotten set on each queue, and the ixgbe_handle_queue() function was continuously rescheduling itself via the taskqueue_enqueue. Since all CPUs were busy with their taskqueue threads, the ixgbe_local_timer() function couldn't run to clear the OACTIVE flag. Submitted by: scottl MFC after: 1 week		2012-06-05 18:48:02 +00:00
