Hi everyone,

I am using BPF_MAP_TYPE_HASH in BPF map definition and my program is working  as expected. 

I have read eBPF-map type  BPF_MAP_TYPE_PERCPU_HASH allows for lock free uses of hash-tables in eBPF for high performance needs. 

I am trying to modify BPF map type from BPF_MAP_TYPE_HASH to BPF_MAP_TYPE_PERCPU_HASH. But, when I run the program,  I am getting issues in  BPF map iteration (using bpf_map_get_next_key)

Can someone help me to know any points need to consider to use BPF_MAP_TYPE_PERCPU_HASH map type . 

Thanks,
