net: dsa: bcm_sf2: Fix 64-bits register writes

2015-09-09T21:14:22+00:00

The macro to write 64-bits quantities to the 32-bits register swapped
the value and offsets arguments, we want to preserve the ordering of the
arguments with respect to how writel() is implemented for instance:
value first, offset/base second.

net: dsa: bcm_sf2: Fix ageing conditions and operation

2015-09-09T05:27:35+00:00

The comparison check between cur_hw_state and hw_state is currently
invalid because cur_hw_state is right shifted by G_MISTP_SHIFT, while
hw_state is not, so we end-up comparing bits 2:0 with bits 7:5, which is
going to cause an additional aging to occur. Fix this by not shifting
cur_hw_state while reading it, but instead, mask the value with the
appropriately shitfted bitmask.

The other problem with the fast-ageing process is that we did not set
the EN_AGE_DYNAMIC bit to request the ageing to occur for dynamically
learned MAC addresses. Finally, write back 0 to the FAST_AGE_CTRL
register to avoid leaving spurious bits sets from one operation to the
other.

net: dsa: mv88e6171: add hardware 802.1Q support

2015-09-07T02:50:50+00:00

The Marvell 88E6171 switch is in the 88E6351 family, which supports
802.1Q, thus add support from the generic mv88e6xxx functions.

dsa: mv88e6xxx: Don't poll forced interfaces for state changes

2015-08-31T21:48:02+00:00

When polling for link status, don't consider ports which have a forced
link. Such ports don't monitor their phy or may not even have a phy.

dsa: mv88e6xxx: Set the RGMII delay based on phy interface

2015-08-31T21:48:02+00:00

Some Marvell switches allow the RGMII Rx and Tx clock to be delayed
when the port is using RGMII. Have the adjust_link function look at
the phy interface type and enable this delay as requested.

dsa: mv88e6xxx: Allow speed/duplex of port to be configured

2015-08-31T21:48:01+00:00

The current code sets user ports to perform auto negotiation using the
phy. CPU and DSA ports are configured to full duplex and maximum speed
the switch supports.

There are however use cases where the CPU has a slower port, and when
user ports have SFP modules with fixed speed. In these cases, port
settings to be read from a fixed_phy devices. The switch driver then
needs to implement the adjust_link op, so the port settings can be
set.

net: dsa: mv88e6xxx: set 802.1Q mode to Fallback

2015-08-23T22:54:26+00:00

The current Secure port mode requires the port-based VLANs to also be
valid in the 802.1Q VLAN Table Unit. The current hardware bridging
support only configures the port-based VLANs, thus is broken.

A new patchset is required to adapt the hardware bridging code to fully
support the Secure port mode.

In the meantime, change the 802.1Q mode of every ports to Fallback,
which filtering is more permissive, and doesn't add this restriction to
handle port-based and tagged-based VLANs.

dsa: mv88e6xxx: Set DSA mode based on chip abilities

2015-08-18T21:17:21+00:00

Older devices only support a single DSA frame format, where as newer
devices have two. Take this into account when configuring a DSA port.
The port needs to be in plain old DSA mode, since this is a DSA link,
where as the newer format can be used for the CPU port.
