net: dsa: add includes for ethtool and phy_fixed definitions

2014-10-18T03:54:46+00:00

net/dsa/slave.c uses functions and structures declared in phy_fixed.h but does not explicitely include it, while dsa.h needs structure declarations for 'struct ethtool_wolinfo' and 'struct ethtool_eee', fix those by including the correct header files.

net: dsa: allow switches driver to implement get/set EEE

2014-09-28T21:14:09+00:00

Allow switches driver to query and enable/disable EEE on a per-port basis by implementing the ethtool_{get,set}_eee settings and delegating these operations to the switch driver. set_eee() will need to coordinate with the PHY driver to make sure that EEE is enabled, the link-partner supports it and the auto-negotiation result is satisfactory.

net: dsa: allow enabling and disable switch ports

2014-09-28T21:14:08+00:00

Whenever a per-port network device is used/unused, invoke the switch driver port_enable/port_disable callbacks to allow saving as much power as possible by disabling unused parts of the switch (RX/TX logic, memory arrays, PHYs...). We supply a PHY device argument to make sure the switch driver can act on the PHY device if needed (like putting/taking the PHY out of deep low power mode).

net: dsa: add {get, set}_wol callbacks to slave devices

Allow switch drivers to implement per-port Wake-on-LAN getter and setters. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: allow switch drivers to implement suspend/resume hooks

2014-09-22T18:41:23+00:00

Add an abstraction layer to suspend/resume switch devices, doing the following split: - suspend/resume the slave network devices and their corresponding PHY devices - suspend/resume the switch hardware using switch driver callbacks Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: allow switch drivers to specify phy_device::dev_flags

2014-09-19T20:27:07+00:00

Some switch drivers (e.g: bcm_sf2) may have to communicate specific workarounds or flags towards the PHY device driver. Allow switches driver to be delegated that task by introducing a get_phy_flags() callback which will do just that. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

dsa: Replace mii_bus with a generic host device

2014-09-15T21:24:20+00:00

This change makes it so that instead of passing and storing a mii_bus we instead pass and store a host_dev. From there we can test to determine the exact type of device, and can verify it is the correct device for our switch. So for example it would be possible to pass a device pointer from a pci_dev and instead of checking for a PHY ID we could check for a vendor and/or device ID.

dsa: Split ops up, and avoid assigning tag_protocol and receive separately

2014-09-15T21:24:20+00:00

This change addresses several issues. First, it was possible to set tag_protocol without setting the ops pointer. To correct that I have reordered things so that rcv is now populated before we set tag_protocol. Second, it didn't make much sense to keep setting the device ops each time a new slave was registered. So by moving the receive portion out into root switch initialization that issue should be addressed. Third, I wanted to avoid sending tags if the rcv pointer was not registered so I changed the tag check to verify if the rcv function pointer is set on the root tree. If it is then we start sending DSA tagged frames. Finally I split the device ops pointer in the structures into two spots. I placed the rcv function pointer in the root switch since this makes it easiest to access from there, and I placed the xmit function pointer in the slave for the same reason.

net: dsa: change tag_protocol to an enum

2014-09-13T21:04:35+00:00

Now that we introduced an additional multiplexing/demultiplexing layer with commit 3e8a72d1dae37 ("net: dsa: reduce number of protocol hooks") that lives within the DSA code, we no longer need to have a given switch driver tag_protocol be an actual ethertype value, instead, we can replace it with an enum: dsa_tag_protocol. Do this replacement in the drivers, which allows us to get rid of the cpu_to_be16()/htons() dance, and remove ETH_P_BRCMTAG since we do not need it anymore.

net: dsa: add Broadcom tag RX/TX handler

2014-08-28T05:59:40+00:00

Add support for the 4-bytes Broadcom tag that built-in switches such as the Starfighter 2 might insert when receiving packets, or that we need to insert while targetting specific switch ports. We use a fake local EtherType value for this 4-bytes switch tag: ETH_P_BRCMTAG to make sure we can assign DSA-specific network operations within the DSA drivers.
