Subject: [PATCH v7 net-next 03/13] net: ethernet: ti: ale: modify vlan/mdb api for switchdev
Date: Wed, 20 Nov 2019 00:19:15 +0200 [thread overview]
Message-ID: <20191119221925.28426-4-grygorii.strashko@ti.com> (raw)
In-Reply-To: <20191119221925.28426-1-grygorii.strashko@ti.com>
From: Ilias Apalodimas <ilias.apalodimas@linaro.org>
A following patch introduces switchdev functionality, so modify
ALE engine VLANs/MDBs API:
- cpsw_ale_del_mcast(): update so it will remove only selected ports from
mcast port_mask or delete whole mcast record if !port_mask
- cpsw_ale_del_vlan(): update so it will remove only selected ports from
all VLAN record's masks or delete whole VLAN record if !port_mask
- add cpsw_ale_vlan_add_modify() to add or modify existing VLAN record's
masks
- add cpsw_ale_set_unreg_mcast() for enabling unreg mcast on port VLANs
