The test case is very similar to reuseport_bpf_cpu, only that here
we select socket members based on current numa node id.
# numactl -H
available: 2 nodes (0-1)
node 0 cpus: 0 1 2 3 4 5 12 13 14 15 16 17
node 0 size: 128867 MB
node 0 free: 120080 MB
node 1 cpus: 6 7 8 9 10 11 18 19 20 21 22 23
node 1 size: 96765 MB
node 1 free: 87504 MB
node distances:
node 0 1
0: 10 20
1: 20 10
# ./reuseport_bpf_numa
