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
