It seems to me that ixgbe_handle_que() should only be doing ixgbe_rxeof(). When ever mq_start() is unable to send, it enqueues the new txq_task. Also, this is checked periodically from the timer function as well. I will try an experiment to evaluate only more_rx in ixgbe_msix_que() and change ixgbe_handle_que() to do rx processing only. I will report back findings. Meanwhile it its immediately obvious to anyone what this will break, please let me know. -vijay _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
