Vivien Didelot says: ==================== net: dsa: mv88e6xxx: ops cosmetics This patchset brings no functional changes. It is a first step in a bigger cosmetics change to the driver. It simplifies print messages and polishes data types and chip operations. The next patchs will only prefix and document the port registers macros. Changes in v2: - KISS and simply use dev_* since chip->ds may not be initialized - add reviewers tags ==================== Signed-off-by: -

Marvell chips have a Jumbo Mode to set the maximum frame size (MTU). The mv88e6xxx_ops structure is meant to contain generic functionalities, no driver logic. Change port_jumbo_config to port_set_jumbo_size setting the mode from a given maximum size value. There is no functional changes since we still use 10240 bytes. At the same time, correctly clear all Jumbo Mode bits before writing. Reviewed-by:

All Marvell chips supporting Pause frames limiting use 1-byte value for input and output. Old chips have both bytes adjacent in a 16-bit register. New ones have an indirect table using 8-bit data. The mv88e6xxx library functions (such as in port.c) must not contain driver logic, but only generic helpers. This patch changes the port_pause_config operation for port_pause_limit taking two u8 arguments for input and output limits. There is no functional changes. Reviewed-by:

The mv88e6xxx_ops describe functionalities, regardless their locations (which can be Global1, Global2, or whatever register set.) Rename the g1_set_cpu_port and g1_set_egress_port ops to set_cpu_port and set_egress_port. No functional changes. Signed-off-by:

Reuse the BR_STATE_* values to abstract a port STP state value. This provides shorter names and better control over the DSA switch operation call. Signed-off-by:

As for the frame mode, add a mv88e6xxx_egress_mode enumeration instead of a 16-bit register mask. Reviewed-by:

Vivien Didelot authored
The mv888e6xxx driver accesses a port's netdev mostly for printing. This is bad for 2 reasons: DSA and CPU ports do not have a netdev pointer; it doesn't give us a correct picture of why a DSA driver might need to access a port's netdev. Instead simply use dev_* printing functions with chip->dev (or ds->dev depending on the scope, both guaranteed to exist), with a p%d prefix for the target port. Signed-off-by:

When inheriting tx_flags from one skbuff to another, always apply a mask to avoid overwriting unrelated other bits in the field. The two SKBTX_SHARED_FRAG cases clears all other bits. In practice, tx_flags are zero at this point now. But this is fragile. Timestamp flags are set, for instance, if in tcp_gso_segment, after this clear in skb_segment. The SKBTX_ANY_TSTAMP mask in __skb_tstamp_tx ensures that new skbs do not accidentally inherit flags such as SKBTX_SHARED_FRAG. Signed-off-by:

Currently there's no way to dump the VIF table for an ipmr table other than the default (via proc). This is a major issue when debugging ipmr issues and in general it is good to know which interfaces are configured. This patch adds support for RTM_GETLINK for the ipmr family so we can dump the VIF table and the ipmr table's current config for each table. We're protected by rtnl so no need to acquire RCU or mrt_lock. Signed-off-by:

Previous patch made it unnecessary to map ports to modules before we allocate their struct. We can now therefore pass the port struct to these functions, thereby making them consistent with other functions that operate on ports. Signed-off-by:

In commit be94535f ("mlxsw: spectrum: Make split flow match firmware requirements") we had to modify the port split flow to overcome quirks in the device's firmware. This resulted in asymmetrical code with regards to port creation and removal. The problem in the firmware is long gone and since we can now enforce a minimal firmware version, we can simplify the code and make it symmetric again. Signed-off-by:

Jiri Pirko says: =================== net: Remove support from bridge bypass for mlxsw/rocker drivers Currently setting bridge port attributes and adding FDBs are done via setting the SELF flag which implies unconsistent offloading model. This patch-set fixes this behavior by making the bridge and drivers which are using it to be totally in sync. This implies several changes: - Offloading bridge flags from the bridge code. - Sending notification about FDB add/del to the software bridge in a similiar way it is done for the hardware externally learned FDBs. By making the offloading model more consistent a cleanup is done in the drivers supporting it. This is done in order to remove un-needed logic related to dump operation which is redundant. First add missing functionality to bridge, then clean up the mlxsw/rocker drivers. v1->v2 - Move bridge-switchdev related stuff to br_switchdev.c as suggested by Nik =================== Signed-off-by: -

Remove support for bridge bypass ndos from stacked devices. At this point no driver which supports stack device behavior offload supports operation with SELF flag. The case for upper device is already taken care of in both of the following cases: 1. FDB add/del - driver should check at the notification cb if the stacked device contains his ports. 2. Port attribute - calls switchdev code directly which checks for case of stack device. Signed-off-by: -

When a new static FDB is added to the bridge a notification is sent to the driver for offload. In case of successful offload the driver should notify the bridge back, which in turn should mark the FDB as offloaded. Currently, externally learned is equivalent for being offloaded which is not correct due to the fact that FDBs which are added from user-space are also marked as externally learned. In order to specify if an FDB was successfully offloaded a new flag is introduced. Signed-off-by:

Currently the bridge doesn't notify the underlying devices about new FDBs learned. The FDB sync is placed on the switchdev notifier chain because devices may potentially learn FDB that are not directly related to their ports, for example: 1. Mixed SW/HW bridge - FDBs that point to the ASICs external devices should be offloaded as CPU traps in order to perform forwarding in slow path. 2. EVPN - Externally learned FDBs for the vtep device. Notification is sent only about static FDB add/del. This is done due to fact that currently this is the only scenario supported by switch drivers.
