[dpdk-dev] [PATCH v6 9/9] table: align rte table hash structs for cache line size

[Gowrishankar Muthukrishnan <gowrishankar.m@linux.vnet.ibm.com>]

rte table hash structs rte_bucket_4_8, rte_bucket_4_16 and rte_bucket_4_32 have
to be cache aligned as required by their corresponding hash create functions
rte_table_hash_create_key8_lru etc.
