* | net: break include loop netdevice.h, dsa.h, devlink.hAndrew Lunn2017-03-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.

| * net: bcmgenet: remove bcmgenet_internal_phy_setup()Doug Berger2017-03-221-15/+0

In so doing it broke the reset of the internal PHY devices used by the GENETv1-GENETv3 which required this reset before the UniMAC was enabled. It also broke the internal GPHY devices used by the GENETv4 because the config_init that installed the AFE workaround was no longer occurring after the reset of the GPHY performed by bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). In addition the code in bcmgenet_internal_phy_setup() related to the "enable APD" comment goes with the bcmgenet_mii_reset() so it should have also been removed. Commit bd4060a6108b ("net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()") moved the bcmgenet_phy_power_set() call to the bcmgenet_power_up() function, but failed to remove it from the bcmgenet_internal_phy_setup() function. Had it done so, the bcmgenet_internal_phy_setup() function would have been empty and could have been removed at that time. Commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on") was submitted to correct the functional problems introduced by commit 6ac3ce8295e6 ("net: bcmgenet: Remove excessive PHY reset"). It was included in v4.4 and made available on 4.3-stable. Unfortunately, it didn't fully revert the commit because this bcmgenet_mii_reset() doesn't apply the soft reset to the internal GPHY used by GENETv4 like the previous one did. This prevents the restoration of the AFE work- arounds for internal GPHY devices after the bcmgenet_phy_power_set() in bcmgenet_internal_phy_setup(). This commit takes the alternate approach of removing the unnecessary bcmgenet_internal_phy_setup() function which shouldn't have been in v4.3 so that when bcmgenet_mii_reset() was restored it should have only gone into bcmgenet_power_up(). This will avoid the problems while also removing the redundancy (and hopefully some of the confusion).

* | mqprio: Modify mqprio to pass user parameters via ndo_setup_tc.Amritha Nambiar2017-03-152-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The configurable priority to traffic class mapping and the user specified queue ranges are used to configure the traffic class, overriding the hardware defaults when the 'hw' option is set to 0. However, when the 'hw' option is non-zero, the hardware QOS defaults are used. This patch makes it so that we can pass the data the user provided to ndo_setup_tc. This allows us to pull in the queue configuration if the user requested it as well as any additional hardware offload type requested by using a value other than 1 for the hw value. Finally it also provides a means for the device driver to return the level supported for the offload type via the qopt->hw value. Previously we were just always assuming the value to be 1, in the future values beyond just 1 may be supported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using the internal PHY it must be powered up when the MII is probed or the PHY will not be detected. Since the PHY is powered up at reset this has not been a problem. However, when the kernel is restarted with kexec the PHY will likely be powered down when the kernel starts so it will not be detected and the Ethernet link will not be established. This commit explicitly powers up the internal PHY when the GENET driver is probed to correct this behavior.

| | | | | | | | | | | | | | | | | | | | | | ndo_set_mac_address() passes struct sockaddr * as 2nd parameter to bgmac_set_mac_address() but code assumed u8 *. This caused two bytes chopping and the wrong mac address was configured.

| * net: ethernet: bgmac: init sequence bugJon Mason2017-03-032-9/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a bug in the 'bgmac' driver init sequence that blind writes for init sequence where it should preserve most bits other than the ones it is deliberately manipulating. The code now checks to see if the adapter needs to be brought out of reset (where as before it was doing an IDM write to bring it out of reset regardless of whether it was in reset or not). Also, removed unnecessary usleeps (as there is already a read present to flush the IDM writes).

| | | | | | | | | | | | | | | | | | | | | | Even if bus is not hot-pluggable, devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.
