Message-ID: <20230817112357.25874-4-hkelam@marvell.com> Date: Thu, 17 Aug 2023 16:53:55 +0530 From: Hariprasad Kelam <hkelam@...vell.com> To: <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org> CC: <kuba@...nel.org>, <davem@...emloft.net>, <sgoutham@...vell.com>, <gakula@...vell.com>, <jerinj@...vell.com>, <lcherian@...vell.com>, <sbhatta@...vell.com>, <hkelam@...vell.com>, <naveenm@...vell.com>, <edumazet@...gle.com>, <pabeni@...hat.com> Subject: [net-next Patch 3/5] octeontx2-af: Add validation of lmac With the addition of new MAC blocks like CN10K RPM and CN10KB RPM_USX, LMACs are noncontiguous. Though in most of the functions, lmac validation checks exist but in few functions they are missing. This patch adds the same.
