2018-01-04net: dsa: b53: Turn off Broadcom tags for more switchesFlorian Fainelli1-3/+6
Models such as BCM5395/97/98 and BCM53125/24/53115 and compatible require that we turn on managed mode to actually act on Broadcom tags, otherwise they just pass them through on ingress (host -> switch) and don't insert them in egress (switch -> host). Turning on managed mode is simple, but requires us to properly support ARL misses on multicast addresses which is a much more involved set of changes not suitable for a bug fix for this release.

On BCM58xx devices (Northstar Plus), there is an accelerator attached to port 8 which would only work if we use prepended Broadcom tags. Resolve that difference in our get_tag_protocol() function by setting the appropriate tagging protocol in that case. We need to change b53_brcm_hdr_setup() a little bit now since we can deal with two types of Broadcom tags.

dev->cpu_port is the driver local information that should only be used to look up register offsets for a particular port, when they differ (e.g: IMP port override), but it should certainly not be used in place of the DSA configured CPU port. Since the DSA switch layer calls port_vlan_{add,del}() on the CPU port as well, we can remove the specific setting of the CPU port within port_vlan_{add,del}.

As the comment above the chunk states, the b53 driver attempts to disable the unused ports. But using ds->enabled_port_mask is misleading, because this mask reports in fact the user ports.

2016-11-17net: dsa: b53: Fix VLAN usage and how we treat CPU portFlorian Fainelli1-12/+4
We currently have a fundamental problem in how we treat the CPU port and its VLAN membership. As soon as a second VLAN is configured to be untagged, the CPU automatically becomes untagged for that VLAN as well, and yet, we don't gracefully make sure that the CPU becomes tagged in the other VLANs it could be a member of. This results in only one VLAN being effectively usable from the CPU's perspective. Instead of having some pretty complex logic which tries to maintain the CPU port's default VLAN and its untagged properties, just do something very simple which consists in neither altering the CPU port's PVID settings, nor its untagged settings: - whenever a VLAN is added, the CPU is automatically a member of this VLAN group, as a tagged member - PVID settings for downstream ports do not alter the CPU port's PVID since it now is part of all VLANs in the system This means that a typical example where e.g: LAN ports are in VLAN1, and WAN port is in VLAN2, now require having two VLAN interfaces for the host to properly terminate and send traffic from/to.
