Problem enabling "rules" in PF_RING

Hello all,I was successful at getting PF_RING enabled for my 82599 Intel card, but i'm having some difficulty getting the hardware filtering enabled. It seems that PF_RING never detects that the card is capable of hardware filtering as shown in the hardware documentation section (it never says "Device eth2 DOES support hardware filtering"...). I am attaching my script and the corresponding dmesg output.
I am also getting a warning that DCA is not enabled, even though i have enabled it in BIOS and it appears to be loaded (i'll attach an "lsmod" as well).I am running it on Ubuntu 11.04 Server, kernel version 2.6.38-8-server, Dell R710.Thanks in advance!~Chris

Look at the threads in this list this month ...

http://listgateway.unipi.it/pipermail/ntop-misc/2011-November/thread.html

... in particular "ixgbe and DCA" (Andrew Lehane says DCA was disabled
in the BIOS on his R710; you may also need to update the BIOS) and
"ixgbe not enabling hardware filtering on Intel X520-DA2" (Luca says
it's not supported yet in the latest ixgbe drivers, but they're working
on it).

(For what it's worth, I'm not convinced DCA is even supported on my
5000X chipset; mention of it is strangely absent in the Intel docs for
it. Odd that Linux loads the dca module though!).

Best Wishes,
Chris

Re: Problem enabling "rules" in PF_RING [In reply to]

Thanks for the help, Chris!I was able to pull down the latest drivers through the SVN repository and that fixed my DCA issues with ixgbe. From the other thread, it sounds like hardware filtering isn't quite ready yet for ixgbe, so i guess i'll have to find a way around that for now. Thanks again,~Chris
