Subject: [PATCH net-next 4/9] octeontx2-af: switch: Representor for switch port
Date: Tue, 30 Jun 2026 08:17:10 +0530 [thread overview]
Message-ID: <20260630024715.4124281-5-rkannoth@marvell.com> (raw)
In-Reply-To: <20260630024715.4124281-1-rkannoth@marvell.com>
Extends esw_cfg with a devlink-derived switch id, copies it into
rvu->rswitch on the AF, adds rvu_sw_port_id(), exports
rvu_rep_get_vlan_id().
