From 179c7e893f64195c5b1f12fddf34b1921386837a Mon Sep 17 00:00:00 2001 From: Pavan Nikhilesh Date: Tue, 3 Jul 2018 10:20:41 +0530 Subject: [PATCH] mempool/octeontx: fix pool to aura mapping HW needs each pool to be mapped to an aura set of 16 auras. Previously, pool to aura mapping was considered to be 1:1.
