[dpdk-dev] [PATCH] acl: use rte_calloc for temporary memory allocation

[Vladyslav Buslov]

Acl build process uses significant amount of memory
which degrades performance by causing page walks when memory
is allocated on regular heap using libc calloc.

This commit changes tb_mem to allocate temporary memory on huge pages
with rte_calloc.
