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

[Jesper Wramberg]

Hi again,

The patches worked great and the DPDK bonding API functions with the
ConnectX-3 now.. yay :-)

I have run into some new trouble however and since its related I figured I
would ask here if anyone could help. I am using SR-IOV to create a
dual-port VF. When trying to bond the ports on this VF it seems that DPDK
cannot set the mac address on the slaves. As a result, I am unable to
receive data on the bonded port. As a workaround, I can set the mac address
on the two VF ports manually in Linux using "ip link set <pf interface> vf
0 mac ..." after which I can start DPDK and receive data on the bonded port
as wanted.

Is there a way to allow DPDK to change the mac address so I avoid the
workaround ? I have done some searching but couldn't find anything.

Regards,
Jesper Wramberg
