Subject: [PATCH v2 26/28] common/cnxk: allow lesser inline inbound sa sizes
Date: Fri, 22 Apr 2022 16:17:07 +0530	[thread overview]
Message-ID: <20220422104709.20722-26-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20220422104709.20722-1-ndabilpuram@marvell.com>

Restructure SA setup to allow lesser inbound SA sizes as opposed
to full Inbound SA size of 1024B with max possible Anti-Replay
window. Since inbound SA size is variable, move the memset logic
out of common code.
