Subject: [PATCH 5/7] table: fix verification on hash bucket header alignment
In powerpc systems, rte table hash structs rte_bucket_4_8, rte_bucket_4_16 and
rte_bucket_4_32 are not cache aligned and hence verification on same would fail.
Instead of checking alignment on cpu cacheline, it could equally be tested as
multiple of 64 bytes.
