Hi all
      I want to use 32 cores to process dns requests, which would need 32
rx queues, but the maximum RSS queue of the ethernet controller(Intel
Corporation 82599ES 10-Gigabit SFI/SFP+) is 16. If I can use dcb or flow
director to assign requests to 32 cores?
       The document (http://dpdk.org/doc/guides/nics/overview.html) shows
that ixgbe driver supports DCB and Flow director, but there isn't any
details about.
