net: dsa: b53: Add missing ARL entries for BCM53125

2017-08-11T15:33:56Z

[ Upstream commit be35e8c516c1915a3035d266a2015b41f73ba3f9 ] The BCM53125 entry was missing an arl_entries member which would basically prevent the ARL search from terminating properly. This switch has 4 ARL entries, so add that.

net: dsa: b53: Fix CPU port for 58xx devices

2017-04-24T22:28:56Z

The 58xx devices (Northstar Plus) do actually have their CPU port wired at port 8, it was unfortunately set to port 5 (B53_CPU_PORT_25) which is incorrect, since that is the second possible management port.

net: dsa: b53: Implement software reset for 58xx devices

2017-04-24T22:28:56Z

Implement the correct software reset sequence for 58xx devices by setting all 3 reset bits and polling for the SW_RST bit to clear itself without a given timeout. We cannot use is58xx() here because that would also include the 7445/7278 Starfighter 2 which have their own driver doing the reset earlier on due to the HW specific integration.

net: dsa: b53: Include IMP/CPU port in dumb forwarding mode

2017-04-24T22:28:56Z

Since Broadcom tags are not enabled in b53 (DSA_PROTO_TAG_NONE), we need to make sure that the IMP/CPU port is included in the forwarding decision. Without this change, switching between non-management ports would work, but not between management ports and non-management ports thus breaking the default state in which DSA switch are brought up.

net: dsa: b53: Add support for port mirroring

2017-01-30T20:55:47Z

Add support for configuring port mirroring through the cls_matchall classifier. We do a full ingress or egress capture towards the capture port. Future improvements could include leveraging the divider to allow less frames to be captured, as well as matching specific MAC DA/SA. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: b53: Add mirror capture register definitions

2017-01-30T20:55:47Z

Add definitions for the different Roboswitch registers relevant for ingress and egress mirroring. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: b53: use dsa_port's bridge pointer

2017-01-29T23:42:46Z

Now that DSA exposes the bridge device pointer to which a port belongs, use it when programming the port based VLANs and thus remove the cache. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: pass bridge device when a port leaves

2017-01-29T23:42:46Z

Upon reception of the NETDEV_CHANGEUPPER, a leaving port is already unbridged, so reflect this by assigning the port's bridge_dev pointer to NULL before calling the port_bridge_leave DSA driver operation. Now that the bridge_dev pointer is exposed to the drivers, reflecting the current state of the DSA switch fabric is necessary for the drivers to adjust their port based VLANs correctly. Pass the bridge device pointer to the port_bridge_leave operation so that drivers have all information to re-program their chips properly, and do not need to cache it anymore.

net: dsa: variable number of ports

2017-01-29T23:42:46Z

Change the ports[DSA_MAX_PORTS] array of the dsa_switch structure for a zero-length array, allocated at the same time as the dsa_switch structure itself. A dsa_switch_alloc() helper is provided for that. This commit brings no functional change yet since we pass DSA_MAX_PORTS as the number of ports for the moment. Future patches can update the DSA drivers separately to support dynamic number of ports. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: Pass device pointer to dsa_register_switch

In preparation for allowing dsa_register_switch() to be supplied with device/platform data, pass down a struct device pointer instead of a struct device_node. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller
