net: dsa: b53: Use vlan_filtering property from dsa_switch

2019-05-01T03:05:29+00:00

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.

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

2019-05-01T03:05:29+00:00

Since DSA has recently learned to treat better with drivers that set
vlan_filtering_is_global, doing this is no longer required.

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

2019-05-01T03:05:28+00:00

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.

dsa: Remove phydev parameter from disable_port call

No current DSA driver makes use of the phydev parameter passed to the
disable_port call. Remove it.

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

2019-02-16T04:37:54+00:00

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

2019-02-16T04:37:54+00:00

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

2019-02-16T04:37:54+00:00

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.

net: dsa: b53: Keep CPU port as tagged in all VLANs

2018-10-05T04:52:49+00:00

Commit c499696e7901 ("net: dsa: b53: Stop using dev->cpu_port
incorrectly") was a bit too trigger happy in removing the CPU port from
the VLAN membership because we rely on DSA to program the CPU port VLAN,
which it does, except it does not bother itself with tagged/untagged and
just usese untagged.

Having the CPU port "follow" the user ports tagged/untagged is not great
and does not allow for properly differentiating, so keep the CPU port
tagged in all VLANs.

In both 802.3z and SGMII modes we need to configure the MAC accordingly
to flip between Fiber and SGMII modes, and we need to read the MAC
status from the SGMII in-band control word.
