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: Add an mdio_device structure

2016-01-07T19:31:26Z

Not all devices attached to an MDIO bus are phys. So add an mdio_device structure to represent the generic parts of an mdio device, and place this structure into the phy_device. Signed-off-by: Andrew Lunn 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: Add missing master netdev dev_put() calls

2015-12-07T21:35:50Z

Upon probe failure or unbinding, add missing dev_put() calls. Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller

net: dsa: cleanup resources upon module removal

2015-12-07T21:35:50Z

Make sure that we unassign the master_netdev dsa_ptr to make the packet processing go through the regular Ethernet receive path. Suggested-by: Florian Fainelli Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller

net: dsa: remove DSA link polling

2015-12-07T21:35:49Z

Since no more DSA driver uses the polling callback, and since the phylib handles the link detection, remove the link polling work and timer code. Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller
