Subject: [PATCH v2 07/21] common/cnxk: support to enable AURA tail drop for RQ
Date: Wed, 23 Feb 2022 01:04:58 +0530 [thread overview]
Message-ID: <20220222193512.19292-7-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20220222193512.19292-1-ndabilpuram@marvell.com>
Add support to enable AURA tail drop via RQ specifically
for inline device RQ's pkt pool. This is better than RQ
RED drop as it can be applied to all RQ's that are not
having security enabled but using same packet pool.
