2016-07-05cdc_ncm: workaround for EM7455 "silent" data interfaceBjørn Mork1-0/+7
Several Lenovo users have reported problems with their Sierra Wireless EM7455 modem. The driver has loaded successfully and the MBIM management channel has appeared to work, including establishing a connection to the mobile network. But no frames have been received over the data interface. The problem affects all EM7455 and MC7455, and is assumed to affect other modems based on the same Qualcomm chipset and baseband firmware. Testing narrowed the problem down to what seems to be a firmware timing bug during initialization. Adding a short sleep while probing is sufficient to make the problem disappear. Experiments have shown that 1-2 ms is too little to have any effect, while 10-20 ms is enough to reliably succeed.

2016-07-02mlxsw: spectrum: Add traps needed for router implementationJiri Pirko2-0/+30
ip2me: To instruct HW to send trapped ip2me traffic to kernel, we have to add this trap. Selection ip2me traffic is introduced later on in this set. ARPs: We are going to stop flooding to CPU port when netdev isn't bridged and only get packets destined to the netdev's IP address and certain control packets. Add traps for ARP request (broadcast) and response (unicast) in order to get these to the CPU and resolve neighbours. host miss: If a packet is routed through a directly connected route and its destination IP is not in the device's neighbour table, then we need to trap it to CPU. This will cause the host to resolve the MAC of the neighbour, which will be eventually programmed to the device's table. router ingress: In order to trap packets in router part.

2016-07-02mlxsw: spectrum: Use action 'discard' when removing trapsIdo Schimmel1-2/+2

However, result is the same, as packets are not trapped to the CPU. In the future we will be able to reverse the operation properly by detaching the trap group from the CPU.

2016-07-02mlxsw: spectrum: Add router interface structIdo Schimmel2-0/+22
When enabling the router in the device we will represent L3 netdevs using router interfaces (RIFs). These will be specified whenever programming routes or neighbours on the netdev. Introduce the basic RIF infrastructure which allows one to lookup a RIF by its netdev. Later patches in the series will extend this, but the basic routines are needed now in order to direct traffic to CPU. Pointers to the RIF structs are stored in an array indexed by the RIF's number. This will allow us to efficiently update the kernel's neighbour table when regularly dumping the device's table.

2016-07-02mlxsw: spectrum: Initialize ports at the end of init sequenceIdo Schimmel1-14/+11
During ports initialization a net device is registered for each available port, which implies the port is usable. However, a port is only usable after the different parts of the device (e.g. flooding, buffers) are initialized. This is especially important now, when we must initialize the router before the ports, as otherwise the device can't be initialized. Solve that by initializing the switch ports at the end of init sequence. Also, remove an unnecessary warning about port up/down events, which would otherwise be invoked whenever removing the driver, as ports are removed before unregistering the listener for these events.

2016-07-02mlxsw: spectrum: Remove RIF from PVID vPort when joining / leaving LAGIdo Schimmel1-0/+13
We are going to assign router interfaces (RIFs) to netdevs if an IPv4 address was assigned to them. If one was assigned to a port netdev, this will translate to the PVID vPort being member in a RIF. While it's possible for a LAG slave to have an IP address, we can't have a vPort being member in two FIDs (assuming the LAG device will be put in bridge / assigned an IP address). Solve that by making the PVID vPort leave any FID it might be a member in when joining / leaving LAG. Note that the PVID vPort is the only vPort that can be present on the port when it's put under LAG.

When VLAN devices are created on top of LAG, their underlying vPorts are configured correctly with LAG membership. However, the PVID vPort is implicit and already present when the port netdev is put under LAG, so its LAG membership is never set. Set it correctly when joining / leaving LAG. This didn't matter until now, but we are going to introduce support for router interfaces (RIFs), which need to take into account LAG membership.

2016-07-02mlxsw: spectrum: Remove VLANs configuration via SELF flagIdo Schimmel3-66/+6
When port isn't bridged it is still possible to invoke switchdev ops and configure the device's VLAN filters. However, this will require us to use different Router InterFaces (RIFs) for the same netdev, instead of one per-netdev as with any other configuration. Taking the above into account and the fact that this functionality is questionable with regards to the device's normal use-case, remove it and instead return an error.

2016-07-02mlxsw: spectrum: Send untagged packets through a port netdevIdo Schimmel1-1/+2
Port netdevs (e.g. swXpY) that are not bridged are represented in the device using a vPort with VID=PVID=1 (the PVID vPort), as untagged packets entering the switch are internally tagged with the PVID VLAN. When these packets are routed through a different port netdev they should egress untagged. This wasn't a problem until now, as non-bridged traffic only originated from the CPU, which transmits packets out of the port as-is. When a vPort is created with VID 1 mark it as egress untagged.
