Hi Xiaolong, Played around a bit and found that for the 2nd vdev that was failing, ./tools/lib/bpf/xsk.c:xsk_create_bpf_maps() was succeeding for "qidconf_map", but failing for "xsks_map" map creation. Guessed could be related to memory.
Tried increasing the max locked memory as suggested in many bpf links available in net, with "ulimit -l 128", and I am able to run testpmd with two vdev Thanks much for the help. Regards, Jags
