No. fec_stats is an array of structs, each struct has car arrsy and integer, and size of that is definitely not bytes. ARRAY_SIZE(fec_stats) is number of stats, i.e. it is returned from fec_enet_get_sset_count() Each stat in blob is u64. Thus (ARRAY_SIZE(fec_stats) * sizeof(u64)) is size of stats blob.
