Subject: [dpdk-stable] [PATCH 20.11] net/octeontx2: fix default MCAM allocation size
Date: Thu, 29 Jul 2021 09:43:56 +0530	[thread overview]
Message-ID: <20210729041356.2053698-1-psatheesh@marvell.com> (raw)

From: Satheesh Paul <psatheesh@marvell.com>

[ upstream commit d81cea5280112f5f6c8796c2fb0bad72bf29d41e ]

Preallocation of MCAM entries is not valid anymore since the
AF side MCAM allocation scheme has changed. This patch disables
preallocation by changing the default MCAM preallocation size
from 8 to 1.

Fixes: 168c59cfe42 ("net/octeontx2: add flow MCAM utility functions")
