[dpdk-dev] Segmentation fault when bonding ports on Mellanox ConnectX-3

[Olga Shern]

For the sake of clarity, I assume you mean the patches about:
"eal: new interrupt handler type"
"mlx4: handle interrupts"
[Olga ] Yes, you are right

Hi Jesper,

Bonding pmd is not supported with dpdk 2.1 on Mellanox nic
We just sent patches to support async link events. Without these patches it will  not work.

Subject: [dpdk-dev] Segmentation fault when bonding ports on Mellanox ConnectX-3

Hi all,

I was wondering if anyone has any experience with the ConnectX-3 card from
Mellanox ? I have a server with such a card I can't seem to get link
bonding to work.

I've installed the necessary kernel modules, etc. and the card works as
expected when testing it using e.g. the layer 2 forwarding example. If i
try to run the bond example, however, I get a segmentation fault when the
"rte_eth_bond_slave_add" function is called. Originally I wanted to bond
the ports using the EAL cmd line option but the card only has one pci
address :(

Does anyone have any idea what could be causing this behavior ?
I am running fw version 2.30.x which I have considered upgrading. Besides
this I have been wondering if I have to do anything in Linux since the PMD
uses the Linux drivers for control. I haven't been able to find any
information on it though.

Regards,
Jesper Wramberg
