[dpdk-dev] [PATCH] librte_hash: Fix compile errors on IBM POWER

[Chao Zhu <chaozhu@linux.vnet.ibm.com>]

This patch fixes the compile errors caused by lacking of "size_t" definition in rte_hash.h. The
compile error exists on IBM POWER and ARM (see jerin.jacob@caviumnetworks.com's message).

The errors are like:
In file included from /tmp/dpdk/app/test/test_hash_scaling.c:35:0:
/tmp/dpdk/build/include/rte_hash.h:70:70: error: unknown type name ‘size_t’
 typedef int (*rte_hash_cmp_eq_t)(const void *key1, const void *key2, size_t key_len);
                                                                      ^
/tmp/dpdk/build/include/rte_hash.h:120:48: error: unknown type name ‘rte_hash_cmp_eq_t’
 void rte_hash_set_cmp_func(struct rte_hash *h, rte_hash_cmp_eq_t func);
