Hi,
I have built VPP v18.01-rc0 with external DPDK v17.08 for mellanox NIC.
The build is happening successfully.
On executing vpp application is crashing.

(gdb)
The NIC I am using is Mellanox connectX-3 Pro, DPDK PMD mlx4.
Is the crash happening because this NIC is unsupported ?
DPDK has a PMD present for this NIC, how to add support for this NIC in VPP
?
Thanks,
Devendra
