    X520 Hardware Filter

    Freaky256

      Hey everybody,

      I installed the PF_RING with DNA on my Ubuntu machine here the details for that:

       

      Linux 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:13:04 UTC 2012 i686 GNU/Linux
      

       

      and the module ixgbe:

       

      modinfo ixgbe
      filename:       /lib/modules/2.6.32-38-generic/kernel/drivers/net/ixgbe/ixgbe.ko
      version:        3.6.7-DNA
      license:        GPL
      description:    Intel(R) 10 Gigabit PCI Express Network Driver
      

       

      Now I want to use the hardware filter also but I'm kinda unable to get it to work...

      I inserted the module with:

       

      insmod ixgbe.ko FdirMode=2,2,2,2 FdirPballoc=3,3,3,3
      

      and the filter mode should be enabled now which I can see in this output:

       

      dmesg
      [   10.584225] ixgbe: 0000:01:00.1: ixgbe_check_options: FCoE Offload feature enabled
      [ 1518.744239] ixgbe: 0000:01:00.1: ixgbe_check_options: Flow Director perfect filtering enabled
      [ 1518.744244] ixgbe: 0000:01:00.1: ixgbe_check_options: Flow Director will be allocated 256kB of packet buffer
      [ 1518.744246] ixgbe: 0000:01:00.1: ixgbe_check_options: FCoE Offload feature enabled
      

       

      The command

      ethtool ethX -K ntuple on
      

      works also fine, but when I try to get a look at the current filters with:

       

      ethtool -u ethX
      

      I get:

      Cannot get driver strings info: Operation not supported

       

      Has anybody an idea what I'm doing wrong?
