net: dsa: b53: Do not clear existing mirrored port mask

2019-11-10T10:34:51Z

[ Upstream commit c763ac436b668d7417f0979430ec0312ede4093d ] Clearing the existing bitmask of mirrored ports essentially prevents us from capturing more than one port at any given time. This is clearly wrong, do not clear the bitmask prior to setting up the new port.

net: dsa: b53: Disable all ports on setup

2019-06-28T20:34:13Z

A b53 device may configured through an external EEPROM like the switch device on the Lamobo R1 router board. The configuration of a port may therefore differ from the reset configuration of the switch. The switch configuration reported by the DSA subsystem is different until the port is configured by DSA i.e. a port can be active, while the DSA subsystem reports the port is inactive. Disable all ports and not only the unused ones to put all ports into a well defined state. Signed-off-by: Benedikt Spranger Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: b53: Use vlan_filtering property from dsa_switch

2019-05-01T03:05:29Z

While possible (and safe) to use the newly introduced dsa_port_is_vlan_filtering helper, fabricating a dsa_port pointer is a bit awkward, so simply retrieve this from the dsa_switch structure. Signed-off-by: Vladimir Oltean Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: b53: Let DSA call .port_vlan_filtering only when necessary

2019-05-01T03:05:29Z

Since DSA has recently learned to treat better with drivers that set vlan_filtering_is_global, doing this is no longer required. Signed-off-by: Vladimir Oltean Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: b53: Let DSA handle mismatched VLAN filtering settings

2019-05-01T03:05:28Z

The DSA core is now able to do this check prior to calling the .port_vlan_filtering callback, so tell it that VLAN filtering is global for this particular hardware. Signed-off-by: Vladimir Oltean Suggested-by: Florian Fainelli Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: b53: Do not program CPU port's PVID

2019-02-16T04:37:54Z

The CPU port is special and does not need to obey VLAN restrictions as far as untagged traffic goes, also, having the CPU port be part of a particular PVID is against the idea of keeping it tagged in all VLANs.

net: dsa: b53: Properly account for VLAN filtering

2019-02-16T04:37:54Z

VLAN filtering can be built into the kernel, and also dynamically turned on/off through the bridge master device. Allow re-configuring the switch appropriately to account for that by deciding whether VLAN table (v_table) misses should lead to a drop or forward.

net: dsa: b53: Fix default VLAN ID

2019-02-16T04:37:54Z

We were not consistent in how the default VID of a given port was defined, b53_br_leave() would make sure the VLAN ID would be either 0/1 depending on the switch generation, but b53_configure_vlan(), which is the default configuration would unconditionally set it to 1. The correct value is 1 for 5325/5365 series and 0 otherwise. To avoid repeating that mistake ever again, introduce a helper function: b53_default_pvid() to factor that out.
