Post #3 of 3
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

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.
