Getting (WARNING: requested port 0 not present - ignoring) while running dpdk

Question

I have tried to run dpdk in my redhat6.3 verison.

Ports are there, but still i can't run dpdk using "0000:43:00.0 '82599EB"

what is the problem ?

Same configuration i am using to run DPDK for 0000:46:00.0 and 0000:43:00.0. but the above 82599EB NIC is not running why?

The same time Dpdk is able to run with 0000:46:00.0 'Device 155d' [This LOGS are below]

Creating mbuf pool 'MProc_pktmbuf_pool' [46080 mbufs] ...

Looks like the logs are incomplete. Please include complete logs, including the command line arguments you are using to run the DPDK app. — Andriy Berestovskyy

imagefile -coreId 5 -socket 0 -c 20 -n 4 --proc-type=primary --socket-mem=512,0,0,0 -b 0:01:0.0 -b 0:01:0.1 -b 0:01:0.2 -b 0:01:0.3 -b 0:46:0.0 -b 0:46:0.1 -b 0:41:0.0 -b 0:41:0.1 -b 0:07:00.0 -b 0:07:00.1 -b 0:03:0.0 -b 0:03:0.1 -b 0:05:0.0 -b 0:05:0.1 -- -p 3 -n

There are few problems with the command line:

The -coreId, -socket is not a valid DPDK command line argument. That is probably your app custom arguments?
The --proc-type is used for multiprocess application, usually we don't need this option.
The --socket-mem=512,0,0,0 allocates 512MB on NUMA node 0 and zero on nodes 1-3. But please note, that some of your NICs are on NUMA node 1 in fact, so we need to allocate some memory there as well.
Instead of a bunch of -b (blacklist) options we can use just one or two -w (whitelist)

Still it does not explain why there is no 0000:43:00.0 device appeared. So pease try to add --log-level=debug to see what is happening to this device.
