[dpdk-stable] [PATCH v2] app/testpmd: fix to add offloads confguration for queue

[Zhao1, Wei]

Hi,  Marchand

  That is my list for this issue.
Yes, I have also fix tx related code, but this test case is for rx offloads.



Environment
·         DPDK version:
19.05.0-rc4
·         NIC hardware: i40e, ixgbe
Test Setup

export RTE_TARGET=x86_64-native-linuxapp-gcc
export RTE_SDK=`pwd`
make -j 62 install T=x86_64-native-linuxapp-gcc
modprobe uio
rmmod -f igb_uio
insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
usertools/dpdk-devbind.py --force --bind=igb_uio 0000:03:00.0 0000:03:00.1
On DUT:
./x86_64-native-linuxapp-gcc/app/testpmd -c 0x6 -n 4  -- -i --portmask=0x1 --port-topology=loop --disable-crc-strip
port stop all
port config all crc-strip on
port start all


The output is:
Configuring Port 0 (socket 0)
Ethdev port_id=0 rx_queue_id=0, new added offloads 0x10000 must be within per-queue offload capabilities 0x1 in rte_eth_rx_queue_setup()
Fail to configure port 0 rx queues

Adding more Cc for double check.

Did not check the code yet, but the Fixes: line is about RX offloads, and you touched both rx and tx offloads.
The incriminated commit comes from 18.02.

I can't reproduce your issue with ixgbe ports.

In 18.11, testpmd starts fine and accepts the configuration change.
In master (before this change), I can see a different issue which has to do with global offloads vs per queue offloads:

Can you describe your setup, like which driver is used, and the full traces of testpmd ?

Thanks.
