net: dsa: Unregister slave_dev in error path

2016-02-18T03:05:16Z

With commit 0071f56e46da ("dsa: Register netdev before phy"), we are now trying to free a network device that has been previously registered, and in case of errors, this will make us hit the BUG_ON(dev->reg_state != NETREG_UNREGISTERED) condition. Fix this by adding a missing unregister_netdev() before free_netdev(). Fixes: 0071f56e46da ("dsa: Register netdev before phy") Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: remove phy_disconnect from error path

2016-02-16T21:04:08Z

The phy has not been initialized, disconnecting it in the error path results in a NULL pointer exception. Drop the phy_disconnect from the error path. Signed-off-by: Sascha Hauer Reviewed-by: Andrew Lunn Acked-by: Neil Armstrong Signed-off-by: David S. Miller

dsa: Register netdev before phy

2016-01-07T19:31:26Z

When the phy is connected, an info message is printed. If the netdev it is attached to has not been registered yet, the name 'uninitialised' in the output. By registering the netdev first, then connecting they phy, we can avoid this. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

phy: Add API for {un}registering an mdio device to a bus.

2016-01-07T19:31:26Z

Rather than have drivers directly manipulate the mii_bus structure, provide and API for registering and unregistering devices on an MDIO bus, and performing lookups. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

phy: Centralise print about attached phy

2016-01-07T19:31:25Z

Many Ethernet drivers contain the same netdev_info() print statement about the attached phy. Move it into the phy device code. Additionally add a varargs function which can be used to append additional information. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: move dsa slave destroy code to slave.c

2015-12-07T21:35:50Z

Move dsa slave dedicated code from dsa_switch_destroy to a new dsa_slave_destroy function in slave.c. Add the netif_carrier_off and phy_disconnect calls in order to correctly cleanup the netdev state and PHY state machine.

net: dsa: use switchdev obj for VLAN add/del ops

2015-11-01T20:56:11Z

Simplify DSA by pushing the switchdev objects for VLAN add and delete operations down to its drivers. Currently only mv88e6xxx is affected. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: remove port_fdb_getnext

2015-10-22T14:38:45Z

No driver implements port_fdb_getnext anymore, and port_fdb_dump is preferred anyway, so remove this function from DSA. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: add port_fdb_dump function

2015-10-22T14:38:35Z

Not all switch chips support a Get Next operation to iterate on its FDB. So add a more simple port_fdb_dump function for them. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

switchdev: remove pointers from switchdev objects

2015-10-15T13:09:49Z

When object is used in deferred work, we cannot use pointers in switchdev object structures because the memory they point at may be already used by someone else. So rather do local copy of the value.
