[dpdk-users] Using Realtek NIC with DPDK

[Gadre Nayan]

I am getting following error with my ip_pipeline application Need help:

./build/ip_pipeline -f ./config/ip_firewall.cfg

Not provided any port mask as I am not using any DPDK compatible NICS,
so disabled ports

[APP] Initializing CPU core map ...
PANIC in app_init_core_map():
Cannot create CPU core map
6: [./build/ip_pipeline(_start+0x29) [0x42cf79]]
5: [/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0) [0x7feeb0c1e830]]

Aborted (core dumped)

The config file used is:
[EAL]
log_level = 9

[PIPELINE0]
type = MASTER
core = 0

[PIPELINE1]
type = INGRESS
core = 1
pktq_out = SWQ0

[PIPELINE2]
type = FIREWALL
core = 2
pktq_in = SWQ0
pktq_out = SWQ1
n_rules = 1024
pkt_type = ipv4

[PIPELINE3]
type = EGRESS
core = 3
pktq_in = SWQ1

I changed the hard-coded values of the below call to suit the "lscpu" output.
app->core_map = cpu_core_map_init(1, 2, 2, 0);

Since I have 1 socket, 2 core per socket and 2 threads per core.
Anything I am missing
