X520 Hardware Filter

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?
