[dpdk-dev] [PATCH v2 02/20] bus/fslmc: fix the ring mode to use correct cache settings

[Shreyansh Jain]

From: Youri Querry <youri.querry_1 at nxp.com>

The code was incorrectly using the cache inhibited access.
It shall use cached enabled access for better performance.

Fixes: 293c0ca94c36 ("bus/fslmc: support memory backed portals with QBMAN 5.0")
Cc: stable at dpdk.org
