Hello:
Couple of questions for the 540-Twinville & "testpmd" app:
1. How do I specify multiple receive queues/port -
Used the command line option -rxq=2 and get this error..
*******************
Fail: nb_rxq(2) is greater than max_rx_queues(1)
EAL: Error - exiting with code: 1
Cause: FAIL from init_fwd_streams()
***************************
Orelse, if I specify rxq=1 on command line and try to configure within the app by using
the "port config all rxq 2", I get the same error..as above.
Is there something missing here!!!
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..?
I did this -- "mac_addr add 0 00:00:00:AA:BB:CC" as an additional MAC address (left the default as is)
Can I assume that the TX of port0 will now generate Ethernet frames with 2 different MAC addresses?
Frames with the default SMAC address, and frames with the MAC-address specified above?
Can I use these MAC address as a classifier (using ethertype_filter), to steer frames to queues 0 & 1?
Thanks
