From f477a4696572201cf26534c83a42ec7dc8098fd8 Mon Sep 17 00:00:00 2001 From: Pavan Nikhilesh Date: Sun, 24 Dec 2017 18:17:56 +0530 Subject: [PATCH] mempool/octeontx: fix memory area registration Clean up the dependency between alloc and memory area registration, this removes the need for SLIST data structure and octeontx_pool_list.
