Subject: [net PATCH 8/9] octeontx2-af: fix infinite loop in unmapping counter
Date: Tue, 16 Mar 2021 14:57:12 +0530 [thread overview]
Message-ID: <1615886833-71688-9-git-send-email-hkelam@marvell.com> (raw)
In-Reply-To: <1615886833-71688-1-git-send-email-hkelam@marvell.com>
Current code does not break from loop due to entry value
miscalculation. Hence correct the same.
Fixes: a958dd59("octeontx2-af: Map or unmap NPC MCAM entry and counter")
