Maybe I got it wrong then... I thought you said fanout (of kernel->TAP packets) would affect all fds associated with the TAP interface. How can the application then use multiple queues? Another thing is: For which purposes do applications need multi queue support for TAP, considering the interface is for management traffic only? If single queue suffices, it might make the PMD simpler. On the other hand, it is more important making it simple for the application than making a simple PMD! :-)
