$ build/app/dpdk-testpmd -c 3 --no-huge -m 20 -a 0:0.0 --vdev
net_null1 --vdev net_null2 -- --no-mlockall --total-num-mbufs=2048
--stats-period 1 --display-xstats a,
EAL: Detected 8 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /run/user/114840/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'VA'
max names is 2
^^^^^^^^^^^^^^

Useless printf debug.
I can remove it when applying.


testpmd: create a new mbuf pool <mb_pool_0>: n=2048, size=2176, socket=0
testpmd: preferred mempool ops selected: ring_mp_mc
Configuring Port 0 (socket 0)
Port 0: 26:45:E7:40:23:6E
Configuring Port 1 (socket 0)
Port 1: BA:5B:47:48:E6:AC
Checking link statuses...
No xstat 'a' on port 0 - skip it
No xstat 'a' on port 1 - skip it
Done
No xstat 'a' on port 0 - skip it
No xstat 'a' on port 1 - skip it
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

xstats are resolved twice (at least?) per port.
This is harmless afaics.
Can you double check?


No commandline core given, start packet forwarding
io packet forwarding - ports=2 - cores=1 - streams=2 - NUMA support
enabled, MP allocation mode: native
