[dpdk-users] testpmd: [mlx4] rxq_add_flow(): flow configuration failed, errno=38: Function not implemented

[Ruslan Osmanov]

Hi,

I need help. DPDK applications fail to start with Mellanox ConnectX-3
NIC. All of them complain about 'not implemented' function when trying
to setup the RX queue:

sudo -E ~/DPDK/x86_64-native-linuxapp-gcc/build/app/test-pmd/testpmd \
-c 0x3 --pci-blacklist 0000:00:06.0 \
--no-huge --proc-type=auto \
-- -i --total-num-mbufs=2048

...

rxq_setup(): 0x921a20: disabling scattered packets support (128 WRs)

The whole output is in the attached dpdk-mlx4-testmpd.log file. If for
some reason the mailing list doesn't support attachments, here is an
online version: https://gist.github.com/7f740489da77ecd23cc162da5e7f864c

DPDK version: 16.04.
dpdk_proc_info:
 sudo -E
 ~/DPDK/x86_64-native-linuxapp-gcc/build/app/proc_info/dpdk_proc_info
 -c 0x3 --no-huge --proc-type=auto --pci-blacklist 0000:00:06.0 -- -p
 0x3 -m --stats --xstats
(output is in the attached dpdk-mlx4-dpdk_proc_info.log; online version:
https://gist.github.com/e8a01484a02e147f9539e81638198747)

Please help me to figure out what's wrong with ... what? I even don't
know. Maybe the mlx4 driver is buggy, maybe dpdk, maybe my
configuration is wrong.
