Subject: Re: [PATCH net-next v3 13/13] net: switchdev: Remove bridge bypass
support from switchdev
On 6.8.2017 15:15, Arkadi Sharshevsky wrote:
> Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded
> through the bridge code, making the switchdev's SELF bridge bypass
> implementation to be redundant. This implies several changes:
> - No need for dump infra in switchdev, DSA's special case is handled
> privately.
> - Remove obj_dump from switchdev_ops.
> - FDBs are removed from obj_add/del routines, due to the fact that they
> are offloaded through the bridge notification chain.
> - The switchdev_port_bridge_xx() and switchdev_port_fdb_xx() functions
