Hello:

=20

Couple of questions for the 540-Twinville & "testpmd" app:

=20

1.       How do I specify multiple receive queues/port -

=20

Used the command line option -rxq=3D2 and get this error..

=20

*******************

Fail: nb_rxq(2) is greater than max_rx_queues(1)

EAL: Error - exiting with code: 1

  Cause: FAIL from init_fwd_streams()

***************************

               =20

                Orelse, if I specify rxq=3D1 on command line and try to con=
figure within the app by using=20

                the "port config all rxq 2", I get the same error..as above=
.

=20

Is there something missing here!!!

=20

=20

2.       If I use the igb_uio (dpdk driver), I am able to configure rxq >1.

My configuration: loopback cable between port0 and port1

Question a: How do I generate TX packets with multiple MAC address..?

               =20

I did this -- "mac_addr add 0 00:00:00:AA:BB:CC" as an additional MAC addre=
ss (left the default as is)

               =20

                Can I assume that the TX of port0 will now generate Etherne=
t frames with 2 different MAC addresses?

                Frames with the default SMAC address, and frames with the M=
AC-address specified above?

=20

                Can I use these MAC address as a classifier (using ethertyp=
e_filter), to steer frames to queues 0 & 1?

=20

                               =20

               =20

Thanks
