Subject: [PATCH net] octeontx2-pf: fix invalid aura pointer free
Date: Thu, 3 Sep 2026 20:09:41 +0530 [thread overview]
Message-ID: <20260903143941.2698880-1-nshettyj@marvell.com> (raw)
From: Geetha sowjanya <gakula@marvell.com>
Do not free empty or uninitialized buffer addresses to the aura.
This avoids freeing bad pointers during receive buffer cleanup.
Fixes: ef6c8da71eaf ("octeontx2-pf: cn10K: Reserve LMTST lines per core")
