When a DSA switch driver is unloaded, the lock on the tag driver should be released so the module can be unloaded. Add the needed calls, but leave the actual release code as a stub. Signed-off-by:

dsa_resolve_tag_protocol() is used to find the tagging driver needed by a switch driver. When the tagging drivers become modules, it will be necassary to take a reference on the module to prevent it being unloaded. So rename this function to _get() to indicate it has some locking properties. Signed-off-by:

A DSA tag driver module will need to register the tag protocols it implements with the DSA core. Add macros containing this boiler plate. The registration/unregistration code is currently just a stub. A Later patch will add the real implementation. Signed-off-by:

In order that we can match the tagging protocol a switch driver request to the tagger, we need to know what protocol the tagger supports. Add this information to the ops structure. Signed-off-by:

All the tag drivers are some variant of GPL. Add a MODULE_LICENSE() indicating this, so the drivers can later be compiled as modules. Signed-off-by:

When the tag drivers become modules, we will need to dynamically load them based on what the switch drivers need. Add aliases to map between the TAG protocol and the driver. In order to do this, we need the tag protocol number as something which the C pre-processor can stringinfy. Only the compiler knows the value of an enum, CPP cannot use them. So add #defines.

Rather than keep a list to map a tagger ops to a name, place the name into the ops structure. This removes the hard coded list, a step towards making the taggers more dynamic. Signed-off-by:

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-04-28 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Introduce BPF socket local storage map so that BPF programs can store private data they associate with a socket (instead of e.g. separate hash table), from Martin. 2) Add support for bpftool to dump BTF types. This is done through a new `bpftool btf dump` sub-command, from Andrii. 3) Enable BPF-based flow dissector for skb-less eth_get_headlen() calls which was currently not supported since skb was used to lookup netns, from Stanislav. 4) Add an opt-in interface for tracepoints to expose a writable context for attached BPF programs, used here for NBD sockets, from Matt. 5) BPF xadd related arm64 JIT fixes and scalability improvements, from Daniel. 6) Change the skb->protocol for bpf_skb_adjust_room() helper in order to support tunnels such as sit. Add selftests as well, from Willem. 7) Various smaller misc fixes. ==================== Signed-off-by: -

Andrew Lunn says: ==================== mv88e6060 cleanups This patchset performs some cleanups of the mv88e6060 DSA driver, as a step towards making it an MDIO device, rather than use the old probing method. The changes here are all pretty mechanical and only compile tested. ==================== Signed-off-by: -

The ibmvnic driver currently uses the same fixed name when using request_irq, this makes it hard to parse when multiple VNIC devices are available at the same time. This patch adds the unit_address as the device identification along with an id for each queue. The original idea was to use the interface name as an identifier, but it is not feasible given these requests happen at adapter probe, and at this point netdev is not yet registered so it doesn't have the proper name assigned to it.

Grygorii Strashko says: ==================== net: ethernet: ti: clean up and optimizations This is a preparation series for introducing new switchbase TI CPSW driver which was originally introduced [1][2] by Ilias Apalodimas <ilias.apalodimas@linaro.org> and also discussed in private mails and at Netdev x13 confernce. Following discussions and suggestions (mostly by Andrew and Ivan) we going to introduce the new driver which is operating in dual-emac mode by default, thus working as 2 individual network interfaces. When both interfaces joined the bridge - CPSW driver will enter a switch mode and discard dual_mac configuration. The CPSW will be switched back to dual_mac mode if any port leaves the bridge. All configuration is going to be implemented via switchdev API. Hence overall change is already very big I'm sending prerequisite patches which are mostly minor fixes/clean ups and code refactoring to separate common parts to be reused by both drivers. Probably the most serious change from functional point of view is Patch 11. These patches were NFS boot tetested on TI AM335x/AM437x/AM5xx boards. These patches can be found at: git@git.ti.com:~gragst/ti-linux-kernel/gragsts-ti-linux-kernel.git branch: lkml-5.1-cpsw-clean-up-v2 changes in v2: - added new patch 16 to get rid of force type conversation - other chages metioned in patches ==================== Signed-off-by: -

As a preparatory patch to add support for a switchdev based cpsw driver, move common ethtool functions to separate cpsw-ethtool.c file so that they can be used across both drivers. It will simplify CPSW driver code maintenance also. Signed-off-by:

Switch CPSW driver to use the new MAC SL API. Signed-off-by:
-
Grygorii Strashko authored
The MAC SL submodule has a lot of common functions between many of TI SoCs AM335x/AM437x/DRA7(AM57xx), Keystone 2 66AK2HK/E/L/G and K3 AM654, but there are also differences especially in registers offsets and sets of supported functions. This patch introduces the MAC SL submodule API which is intended to provide a common way to access the MAC SL submodule and hide HW integrations details. Signed-off-by:

As a preparatory patch to add a switchdev based cpsw driver move the common header definitions to cpsw_priv.h. The plan is to develop a new driver on switchdev driver model and obsolete the current cpsw driver after all required functions are added to the new driver. This patch allows the same header file to be re-used on both drivers during the transition period. Signed-off-by:

The Davinci MDIO in most of the case implemented as module inside of TI CPSW subsystem and fully depends on CPSW to be enabled, but historically it's implemented as separate Platform device/driver and defined in DT files in two ways: - as standalone node - as child node of CPSW subsystem. In later case it's required to split CPSW subsystem "reg" property to exclude MDIO I/O range which is not useful. Hence, replace devm_ioremap_resource() with devm_ioremap() to allow define full I/O range in parent CPSW subsystem without spliting. Signed-off-by:

Grygorii Strashko authored
Now CPSW ALE will set/clean Host port bit in Unregistered Multicast Flood Mask (UNREG_MCAST_FLOOD_MASK) for every VLAN without checking if this port belongs to VLAN or not when ALLMULTI mode flag is set for nedev. This is working in non dual_mac mode, but in dual_mac - it causes enabling/disabling ALLMULTI flag for both ports. Hence fix it by adding additional parameter to cpsw_ale_set_allmulti() to specify ALE port number for which ALLMULTI has to be enabled and check if port belongs to VLAN before modifying UNREG_MCAST_FLOOD_MASK.
