Subject: [PATCH 07/10] net/cnxk: fix issue with outbound security higher pkt burst
Date: Fri, 17 May 2024 13:14:45 +0530	[thread overview]
Message-ID: <20240517074448.3146611-7-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20240517074448.3146611-1-ndabilpuram@marvell.com>

Fix issue with outbound security path while handling mixed traffic i.e
both plain and inline outbound pkts being present as part of burst
and burst size is > 32. The loop needs to be broken when
we don't have space for 4 pkts in LMT lines for CPT considering
both the full lmt lines and partial lmt lines used.

Fixes: 55bfac717c72 ("net/cnxk: support Tx security offload on cn10k")
