Subject: [PATCH net-next 4/8] net: ethernet: ti: cpsw_ale: add cpsw_ale_vlan_del_modify()
Date: Thu, 1 Oct 2020 13:52:54 +0300	[thread overview]
Message-ID: <20201001105258.2139-5-grygorii.strashko@ti.com> (raw)
In-Reply-To: <20201001105258.2139-1-grygorii.strashko@ti.com>

Add/export cpsw_ale_vlan_del_modify() and use it in cpsw_switchdev instead
of generic cpsw_ale_del_vlan() to avoid mixing 8021Q and switchdev VLAN
offload. This is preparation patch equired by follow up changes.
