2018-07-19mlxsw: spectrum: Add KVDL manager implementation for Spectrum-2Jiri Pirko
In Spectrum-2, KVD linear indexes are hashed into KVD hash. Therefore it is possible for multiple resource types to use same indexes. There are multiple index spaces. Also, the index space is bigger than the actual KVD hash area, which allows to have holes in the index space without any penalization. The HW has to be told in case the index for particular resource type is no longer used so it can be freed from KVD hash. IEDR register is used for that.

The wrong helper is used to swap the bytes when adding the lower bits of the TX descriptors tag field in the shared ds_tagl variable. The variable contains the DS[11:0] field and then the TAG[3:0] bits. The mistake was highlighted by the sparse warning: ravb_main.c:1622:31: left side has type restricted __le16 ravb_main.c:1622:31: right side has type unsigned short ravb_main.c:1622:31: warning: invalid assignment: |= ravb_main.c:1622:34: warning: cast to restricted __le16 Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S.

2018-07-18ravb: fix shadowing of symbol 'stats' in ravb_get_ethtool_stats()Niklas Söderlund
Inside a loop in ravb_get_ethtool_stats() a variable 'stats' is declared resulting in the argument also named 'stats' to be shadowed. Fix this warning by renaming the unused argument 'stats' to 'estats'. This fixes the sparse warning: ravb_main.c:1225:36: originally declared here ravb_main.c:1233:41: warning: symbol 'stats' shadows an earlier one Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S.

2018-07-18net: dsa: realtek-smi: Add Realtek SMI driverLinus Walleij
This adds a driver core for the Realtek SMI chips and a subdriver for the RTL8366RB. I just added this chip simply because it is all I can test. The code is a massaged variant of the code that has been sitting out-of-tree in OpenWRT for years in the absence of a proper switch subsystem. This creates a DSA driver for it. I have tried to credit the original authors wherever possible. The main changes I've done from the OpenWRT code: - Added an IRQ chip inside the RTL8366RB switch to demux and handle the line state IRQs. - Distributed the phy handling out to the PHY driver. - Added some RTL8366RB code that was missing in the driver at the time, such as setting up "green ethernet" with a funny jam table and forcing MAC5 (the CPU port) into 1 GBit. - Select jam table and add the default jam table from the vendor driver, also for ASIC "version 0" if need be. - Do not store jam tables in the device tree, store them in the driver. - Pick in the "initvals" jam tables from OpenWRT's driver and make those get selected per compatible for the whole system. It's apparently about electrical settings for this system and whatnot, not really configuration from device tree. - Implemented LED control: beware of bugs because there are no LEDs on the device I am using! We do not implement custom DSA tags. This is explained in a comment in the driver as well: this "tagging protocol" is not simply a few extra bytes tagged on to the ethernet frame as DSA is used to. Instead, enabling the CPU tags will make the switch start talking Realtek RRCP internally. For example a simple ping will make this kind of packets appear inside the switch: 0000 ff ff ff ff ff ff bc ae c5 6b a8 3d 88 99 a2 00 0010 08 06 00 01 08 00 06 04 00 01 bc ae c5 6b a8 3d 0020 a9 fe 01 01 00 00 00 00 00 00 a9 fe 01 02 00 00 0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 As you can see a custom "8899" tagged packet using the protocol 0xa2. Norm RRCP appears to always have this protocol set to 0x01 according to OpenRRCP. You can also see that this is not a ping packet at all, instead the switch is starting to talk network management issues with the CPU port. So for now custom "tagging" is disabled. This was tested on the D-Link DIR-685 with initramfs and OpenWRT userspaces and works fine on all the LAN ports (lan0 .. lan3). The WAN port is yet not working.
