dsa: mv88x6xxx: Zero statistics counters

2015-06-23T13:37:17+00:00

Zero the statistics counters when setting up the global
registers. Otherwise the counters will remain from the last boot if
the power has not been removed.

dsa: mv88x6xxx: Add debugfs interface for scratch registers

2015-06-23T13:33:42+00:00

Allow the contents of the scratch registers to be shown in debugfs.

dsa: mv88x6xxx: Add debugfs interface for device map

2015-06-23T13:33:41+00:00

The device map is used to route packets between cascaded switches.
Add dumping a switches device map via debugfs.

dsa: mv88x6xxx: Add debugfs interface for statistics

2015-06-23T13:33:41+00:00

Allow the contents of the statistics counters to be shown in debugfs.
This is particularly useful for the cpu and dsa ports, which cannot be
seen using ethtools -S.

dsa: mv88x6xxx: Refactor getting a single statistic

2015-06-23T13:33:40+00:00

Move the code to retrieve a statistics counter into a function of its
own, so it can later be reused.

net: dsa: bcm_sf2: Utilize BRCM_PSEUDO_PHY_ADDR

2015-06-11T06:33:58+00:00

Utilize the newly introduced BRCM_PSEUDO_PHY_ADDR constant from
brcmphy.h instead of open-coding the Broadcom Ethernet switches
pseudo-PHY address (30).

net: dsa: mv88e6xxx: Fix deadlock by double lock

2015-06-07T19:19:22+00:00

ethtool -S on a DSA interface can deadlock for some switches because
the same lock is taken twice. Use the register read function which
expects the lock to be already held.

net: dsa: bcm_sf2: properly propagate carrier down state for MoCA

2015-05-18T03:40:24+00:00

MoCA interfaces require the use of an user-space daemon (mocad) which
will typically use cmd->autoneg to force the link. This is causing other
network manager applications not to get proper carrier down
notifications because of the following sequence of events:

- link down interrupt is received, link is set to 0 by the interrupt
  handler
- fixed_link update callback runs and updates the BMSR register
  accordingly
- PHY library polls the PHY for link status, sees the link is down,
  proceeds with reporting that
- mocad gets notified of the link state and call phy_ethtool_sset()
  with cmd->autoneg set to the link status (0)
- phy_start_aneg() is called at the end of phy_ethtool_sset() and sets
  the PHY state to PHY_FORCING

Just make sure we notify the interface carrier appropriately when we
detect that the link is down in our fixed_link update callback. This is
made local to the bcm_sf2 driver as the PHY library does the right thing
in any case. This is similar to the GENET change introduced in
54d7c01d3ed699cfc213115eaecfe1175cfaff8f ("net: bcmgenet: enable MoCA
link state change detection").
