Hi,
I'm trying to use Flow Director. Initially I used a X540 chipset and I was not able to make it work; I thought it was a compatibility problem with the controller. Maxime suggested to change some lines in the ixgbe_fdir.c file, I changed these lines but it
did not give the expected results;
At this point I was sure that the problem was the incompatibility between the DPDK and the X540 chipset therefore I retrived a NIC whit a 82599 chipset and I repeated my attempts, unfortunately I got the some problems.
In order to be more clear I explain my attempts:
I try to run the test-pmd app with the command-line option
"--pkt-filter-mode=perfect", the app doesn't start (the rte_eth_dev_start
function return an error) otherwise without the --pkt-filter-mode command-line option the application run
normally.
This is the command line I use to start the program:
frog@frog:~/dpdk-1.5.2r1/app/test-pmd$
sudo ./testpmd -c 0x0f -n 2 -m 512 -- -i --portmask=0x3 --nb-cores=2
--pkt-filter-mode=perfect --rxq=2 --txq=2
and the relative output:
...
Interactive-mode selected
Configuring Port 0 (socket -1)
Fail to start port 0 (ret=-5)*
Configuring Port 1 (socket -1)
Fail to start port 1 (ret=-5)*
Please stop the ports first
Done
testpmd>
*ret=-5 is the result of the rte_eth_dev_start function
I guess someone was able to use FDIR, at least in the testpmd application. What am I doing wrong?
Best regards
