2014-10-28net: dsa: Error out on tagging protocol mismatchesAndrew Lunn1-1/+4
If there is a mismatch between enabled tagging protocols and the protocol the switch supports, error out, rather than continue with a situation which is unlikely to work.

The check for the presence or not of the optional switch function get_phy_flags() called the function, rather than checked to see if it is a NULL pointer. This causes a derefernce of a NULL pointer on all switch chips except the sf2, the only switch to implement this call.

Commit f7f1de51edbd ("net: dsa: start and stop the PHY state machine") add calls to phy_start() in dsa_slave_open() respectively phy_stop() in dsa_slave_close(). We also call phy_start_aneg() in dsa_slave_create(), and this call is messing up with the PHY state machine, since we basically start the auto-negotiation, and later on restart it when calling phy_start(). phy_start() does not currently handle the PHY_FORCING or PHY_AN states properly, but such a fix would be too invasive for this window.

2014-09-15dsa: Replace mii_bus with a generic host deviceAlexander Duyck2-17/+9
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.

2014-09-15dsa: Split ops up, and avoid assigning tag_protocol and receive separatelyAlexander Duyck7-31/+53
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.

2014-09-13net: dsa: change tag_protocol to an enumFlorian Fainelli2-5/+4
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.

2014-08-27net: dsa: allow for more complex PHY setupsFlorian Fainelli3-3/+82
Modify the DSA slave interface to be bound to an arbitray PHY, not just the ones that are available as child PHY devices of the switch MDIO bus. This allows us for instance to have external PHYs connected to a separate MDIO bus, but yet also connected to a given switch port. Under certain configurations, the physical port mask might not be a 1:1 mapping to the MII PHYs mask. This is the case, if e.g: Port 1 of the switch is used and connects to a PHY at a MDIO address different than 1. Introduce a phys_mii_mask variable which allows driver to implement and divert their own MDIO read/writes operations for a subset of the MDIO PHY addresses.

2014-08-27net: dsa: reduce number of protocol hooksFlorian Fainelli6-67/+50
DSA is currently registering one packet_type function per EtherType it needs to intercept in the receive path of a DSA-enabled Ethernet device. Right now we have three of them: trailer, DSA and eDSA, and there might be more in the future, this will not scale to the addition of new protocols. This patch proceeds with adding a new layer of abstraction and two new functions: dsa_switch_rcv() which will dispatch into the tag-protocol specific receive function implemented by net/dsa/tag_*.c dsa_slave_xmit() which will dispatch into the tag-protocol specific transmit function implemented by net/dsa/tag_*.c When we do create the per-port slave network devices, we iterate over the switch protocol to assign the DSA-specific receive and transmit operations. A new fake ethertype value is used: ETH_P_XDSA to illustrate the fact that this is no longer going to look like ETH_P_DSA or ETH_P_TRAILER like it used to be. This allows us to greatly simplify the check in eth_type_trans() and always override the skb->protocol with ETH_P_XDSA for Ethernet switches tagged protocol, while also reducing the number repetitive slave netdevice_ops assignments.

Commit 82167cb8c6b2f8166d5c7532e5ef4b5e0cc46a72 ('net: dsa/slave: Fix compilation warnings') fixed one possible invalid configuration (NET_DSA enabled with no trailer formats) but added others: drivers can select NET_DSA without its dependencies being met. It's not very useful to make either the DSA core or the tagging formats manually selectable without a driver to use them, so: 1. Define a hidden HAVE_NET_DSA option and move the dependencies of NET_DSA to that. While we're at it, drop the deprecated EXPERIMENTAL dependency. 2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA. 3. Hide the tagging format options again. 4. Make drivers select both NET_DSA and the appropriate tagging format option.

2012-05-09dsa: Convert compare_ether_addr to ether_addr_equalJoe Perches1-5/+5
Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting.

2011-11-29dsa: Move switch drivers to new directory drivers/net/dsaBen Hutchings7-1859/+1
Support for specific hardware belongs under drivers/net/ not net/. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Acked-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-29dsa: Move all definitions needed by drivers into <net/dsa.h>Ben Hutchings5-95/+4
Any headers included by drivers should be under include/, and any definitions they use are not really private to the core as the name "dsa_priv.h" suggests.

2011-11-29dsa: Remove unnecessary exportsBen Hutchings1-2/+0
I mistakenly exported functions from slave.c that are only called from dsa.c, part of the same module. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Acked-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-26dsa: Allow core and drivers to be built as modulesBen Hutchings2-7/+11
Change the kconfig types to tristate and adjust the condition for declaring net_device::dsa_ptr to allow for this. Adjust the makefile so that if NET_DSA_MV88E6123_61_65=y and NET_DSA_MV88E6131=m or vice versa then both drivers are built-in. We could leave these options as bool and make NET_DSA_MV88E6XXX a user-selected option, but that would break existing configurations.

2011-11-26mv88e6xxx: Combine mv88e6131 and mv88e612_61_65 driversBen Hutchings5-31/+32
These drivers share a lot of code, so if we make them modular they should be built into the same module. Therefore, link them together and merge their respective module init and exit functions. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-26dsa: Combine core and tagging codeBen Hutchings6-49/+38
These files have circular dependencies, so if we make DSA modular then they must be built into the same module. Therefore, link them together and merge their respective module init and exit functions. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
