Hi,
The series can't recognize i40e device, so testpmd start failed.
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4-8 -n 6 -a 17:00.0 --
-i --txq=2 --rxq=2
<...>
EAL: Probe PCI driver: net_i40e (8086:158b) device: 0000:17:00.0
(socket 0)
EAL: No legacy callbacks, legacy socket not created
testpmd: No probed ethernet devices
Interactive-mode selected
Fail: input txq (2) can't be greater than max_tx_queues (0) of port 0
EAL: Error - exiting with code: 1
Cause: txq 2 invalid - must be >= 0 && <= 0
thanks
