BPF-Maps directory(/sys/fs/bpf/tc/globals/) not being created

[jaysheth2]

In a few instances, we have noticed that although the BPF file system (/sys/fs/bpf) is being mounted appropriately, the complete path (/sys/fs/bpf/tc/globals/) for the BPF maps does not exist. As most of the program the /sys/fs/bpf/tc/globals directory for creation of maps, the program will fail if the complete directory path is not present. Hence, L3AFD needs to make sure that complete path for the maps creation exists, or creates them, such that the programs do not fail.
