Hello Haider,
Besides the info print issue, can you describe what is the use case?
What do you try to achieve and whether you see any issue?

Regards,
Asaf Penso

Subject: mlx5 - shared_rxq not working on some Connect x6 DX

Hi,

I used two servers A and B. Server A has Connect x5 and x6 DX cards while server B has Connect x6 DX card.

I have checked with Connect x5 and x6 DX cards on "server A" and I am able to get below rxq_share device capability:

testpmd> show port info all

Device capabilities: 0x14( RXQ_SHARE FLOW_SHARED_OBJECT_KEEP )

Server A setting:
# ofed_info -s
MLNX_OFED_LINUX-5.4-3.1.0.0:

# ethtool -i enp129s0f0
driver: mlx5_core
version: 5.4-3.1.0
firmware-version: 16.32.1010 (MT_0000000080)
expansion-rom-version:
bus-info: 0000:81:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: yes


But when I moved to server B with another Connect x6 DX card, I could not see this capability.

testpmd> show port info all

Device capabilities: 0x14( FLOW_SHARED_OBJECT_KEEP )

Server B Settings:
# ofed_info -s
MLNX_OFED_LINUX-5.4-3.5.8.0:

# ethtool -i enp132s0f0
driver: mlx5_core
version: 5.4-3.5.8
firmware-version: 22.31.1014 (MT_0000000436)
expansion-rom-version:
bus-info: 0000:84:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: yes


Although server B has higher versions of OFED and firmware, my question is do I need to enable/disable firmware settings? Or are there any other configurations we need to apply?

Regards,
Haider
