Improve detection of addressing mode in e6000sw

2018-04-10T08:35:43Z

Some devices cannot rely on the switch MDIO address passed in the DTB for specifying single/multi-chip addressing mode. Introduce new property "single-chip-addressing" which added to DTS will force single-chip mode.

Clean up OF_getprop_alloc API

2018-04-08T22:59:34Z

OF_getprop_alloc takes element size argument and returns number of elements in the property. There are valid use cases for such behavior but mostly API consumers pass 1 as element size to get string properties. What API users would expect from OF_getprop_alloc is to be a combination of malloc + OF_getprop with the same semantic of return value. This patch modifies API signature to match these expectations. For the valid use cases with element size != 1 and to reduce modification scope new OF_getprop_alloc_multi function has been introduced that behaves the same way OF_getprop_alloc behaved prior to this patch.

[etherswitch] check if_alloc returns NULL

2018-01-24T21:33:18Z

This patch is cosmetic. It checks if allocation of ifnet structure failed. It's better to have this check rather than assume positive scenario. Submitted by: Dmitry Luhtionov Reported by: Dmitry Luhtionov

Fix the port vlan support in e6000 based switches.

2017-07-27T02:38:53Z

Reduce the use of local copies of switch register data. The switch now works with the upstream dsa node (i.e. the upstream DTS). Tested on: ClearFog Pro (88E6176), SG-3100 (88E6141) Sponsored by: Rubicon Communications, LLC (Netgate)

Add support to 2.5G uplink for the MV88E6141 and MV88E6341 switches.

Force the switch port settings for fixed media types. Tested with: 88E6176, 88E6141 Sponsored by: Rubicon Communications, LLC (Netgate)

Prevent multiple lock initialization in e6000sw probe

2017-06-13T18:35:14Z

r319886 ("Add the initial support for the Marvell 88E6141 and 88E6341 switches.") unveiled a problem with possible multiple lock creation. Move its initialization to the driver attach and for obtaining the switch ID create a temprorary one, which is immediately destroyed after the check.

Right now the driver only supports port VLANs, so make sure etherswitch_getinfo() return the proper switch capabilities. Handle the cases where not all ports are in use (that will also require etherswitch cooperation). Sponsored by: Rubicon Communications, LLC (Netgate)

Poll PHY status using internal e6000sw registers

2017-05-19T08:24:23Z

e6000sw family automatically reflects PHY status in each port's registers. Therefore it is not necessary to do a full PHY polling squence, which results in much quicker operation and much less significant usage of the SMI bus. Care must be taken that the resulting ifmedia_active is identical to what the PHY will compute, or gratuitous link status changes will occur whenever the PHYs update function is called. This patch implements above improvement. On the occasion set a pointer to the proc structure to be part of software context instead of being a global variable.
