net: dsa: bcm_sf2: Ensure we re-negotiate EEE during after link change

2016-11-24T20:53:50Z

In case the link change and EEE is enabled or disabled, always try to re-negotiate this with the link partner. Fixes: 450b05c15f9c ("net: dsa: bcm_sf2: add support for controlling EEE") Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: b53: Fix VLAN usage and how we treat CPU port

2016-11-17T04:25:29Z

We currently have a fundamental problem in how we treat the CPU port and its VLAN membership. As soon as a second VLAN is configured to be untagged, the CPU automatically becomes untagged for that VLAN as well, and yet, we don't gracefully make sure that the CPU becomes tagged in the other VLANs it could be a member of. This results in only one VLAN being effectively usable from the CPU's perspective. Instead of having some pretty complex logic which tries to maintain the CPU port's default VLAN and its untagged properties, just do something very simple which consists in neither altering the CPU port's PVID settings, nor its untagged settings: - whenever a VLAN is added, the CPU is automatically a member of this VLAN group, as a tagged member - PVID settings for downstream ports do not alter the CPU port's PVID since it now is part of all VLANs in the system This means that a typical example where e.g: LAN ports are in VLAN1, and WAN port is in VLAN2, now require having two VLAN interfaces for the host to properly terminate and send traffic from/to.

net: dsa: bcm_sf2: Do not rely on kexec_in_progress

2016-10-22T20:17:53Z

After discussing with Eric, it turns out that, while using kexec_in_progress is a nice optimization, which prevents us from always powering on the integrated PHY, let's just turn it on in the shutdown path. This removes a dependency on kexec_in_progress which, according to Eric should not be used by modules Fixes: 2399d6143f85 ("net: dsa: bcm_sf2: Prevent GPHY shutdown for kexec'd kernels") Signed-off-by: Florian Fainelli Signed-off-by: David S.

net: dsa: bcm_sf2: Prevent GPHY shutdown for kexec'd kernels

2016-10-20T18:43:50Z

For a kernel that is being kexec'd we re-enable the integrated GPHY in order for the subsequent MDIO bus scan to succeed and properly bind to the bcm7xxx PHY driver. If we did not do that, the GPHY would be shut down by the time the MDIO driver is probing the bus, and it would fail to read the correct PHY OUI and therefore bind to an appropriate PHY driver. Later on, this would cause DSA not to be able to successfully attach to the PHY, and the interface would not be created at all. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: bcm_sf2: Fix module autoload for OF registration

2016-10-17T17:03:03Z

If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro.

treewide: remove redundant #include

2016-10-11T22:06:33Z

Kernel source files need not include explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.

Introduce a mv88e6xxx_ops structure to describe supported chip-wide functions and assign the correct variant to the chip models. For the moment, add only PHY access routines. This allows to get rid of the PHY ops structures and the usage of PHY flags. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller
