[dpdk-dev] [PATCH] librte_lpm: use field access instead of type conversion.

From: Xuelin Shi struct tbl_entry{ uint8_t next_hop; uint8_t valid :1; uint8_t valid_group :1; uint8_t depth :6 } uint16_t tbl = (uint16_t)tbl_entry; next_hop = (uint8_t)tbl; next_hop cannot get the correct value of the field if the cpu arch is BIG_ENDIAN. change
