Subject: [PATCH] event/cnxk: increase inflight buffer count
Date: Mon, 29 Sep 2025 15:57:53 +0530 [thread overview]
Message-ID: <20250929102753.1036004-1-ktejasree@marvell.com> (raw)
Increasing crypto adapter inflight buffer count as
performance is dropped to zero when high traffic is
sent on 16 or 24 cores in event vector mode.
