net: dsa: mv88e6xxx: Clear the PDOWN bit on setup

2016-03-31T19:12:57+00:00

Some of the vendor-specific bootloaders set up this part
of the initialization for us, so this was never added.
However, since upstream bootloaders don't initialize the
chip specifically, they leave the fiber MII's PDOWN flag
set, which means that the CPU port doesn't connect.

This patch checks whether this flag has been clear prior
by something else, and if not make us clear it.

net: dsa: mv88e6xxx: Introduce _mv88e6xxx_phy_page_{read, write}

2016-03-31T19:12:57+00:00

Add versions of the phy_page_read and _write functions to
be used in a context where the SMI mutex is held.

net: dsa: make port_bridge_leave return void

2016-03-14T20:05:31+00:00

netdev_upper_dev_unlink() which notifies NETDEV_CHANGEUPPER, returns
void, as well as del_nbp(). So there's no advantage to catch an eventual
error from the port_bridge_leave routine at the DSA level.

Make this routine void for the DSA layer and its existing drivers.

net: dsa: rename port_*_bridge routines

2016-03-14T20:05:31+00:00

Rename DSA port_join_bridge and port_leave_bridge routines to
respectively port_bridge_join and port_bridge_leave in order to respect
an implicit Port::Bridge namespace.

dsa: Rename mv88e6123_61_65 to mv88e6123 to be consistent

2016-03-14T19:43:10+00:00

All the drivers support multiple chips, but mv88e6123_61_65 is the
only one that reflects this in its naming. Change it to be consistent
with the other drivers.

net: dsa: mv88e6xxx: avoid writing the same mode

2016-03-10T21:10:31+00:00

There is no need to change the 802.1Q port mode for the same value.
Thus avoid such message:

    [  401.954836] dsa dsa@0 lan0: 802.1Q Mode: Disabled (was Disabled)

net: dsa: mv88e6xxx: read then write PVID

2016-03-10T21:10:30+00:00

The port register 0x07 contains more options than just the default VID,
even though they are not used yet. So prefer a read then write operation
over a direct write.

This also allows to keep track of the change through dynamic debug.

net: dsa: mv88e6xxx: rework port state setter

2016-03-10T21:10:30+00:00

Apply a few non-functional changes on the port state setter:

  * add a dynamic debug message with state names to track changes
  * explicit states checking instead of assuming their numeric values
  * lock mutex only once when changing several port states
  * use bitmap macros to declare and access port_state_update_mask

net: dsa: mv88e6xxx: support VLAN filtering

Implement port_vlan_filtering in the driver to toggle the related port
802.1Q mode between DISABLED and SECURE, on user request.

net: dsa: mv88e6xxx: remove reserved VLANs

2016-03-01T21:24:53+00:00

Now that ports isolation is correctly configured when joining or leaving
a bridge, there is no need to rely on reserved VLANs to isolate
unbridged ports anymore. Thus remove them, and disable 802.1Q on setup.

This restores the expected behavior of hardware bridging for systems
without 802.1Q or VLAN filtering enabled.
