I'm using the Mellanox Connect X5:

pci@0000:3b:00.0  enp59s0f0np0   network        MT27800 Family [ConnectX-5]

This is the message:
lcore 6 called tx_pkt_burst for not ready port 0

I'm having all sorts of problems with this Mellanox stuff, Intel cards are
much more user friendly.

Just to recap:
* configure on primary and transmit on primary           ---> GOOD

* configure on secondary and transmit on secondary  ---> SIGSEGV
Thread 4 "lcore-worker-6" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff4346640 (LWP 7208)]
rte_eth_tx_burst (port_id=0, queue_id=0, tx_pkts=0x7ffff4344ac0, nb_pkts=1)
at /usr/local/include/rte_ethdev.h:5650
5650            qd = p->txq.data[queue_id];
(gdb) print p->txq
$2 = {data = 0x0, clbk = 0x7ffff7f21528 <rte_eth_devices+8296>} (data is
NULL)


* configure on primary and transmit on secondary       ---> PORT NOT READY

Do you know who should be notified of this problem? Should I open a bug on
DPDK bugzilla or file it to NVIDIA?

Thx.
