| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mlxsw: spectrum: Add router interface structIdo Schimmel2016-07-022-0/+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.

* mlxsw: spectrum: Initialize ports at the end of init sequenceIdo Schimmel2016-07-021-14/+11Star
| | | | | | | | | | | | | | | | | | | 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.

* mlxsw: spectrum: Remove RIF from PVID vPort when joining / leaving LAGIdo Schimmel2016-07-021-0/+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.

| | | | | | | | | | | | | | | | | 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.

* mlxsw: spectrum: Send untagged packets through a port netdevIdo Schimmel2016-07-021-1/+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.

* net/mlx5e: Introduce SRIOV VF representorsHadar Hen Zion2016-07-026-19/+574
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the relevant profile functions to create mlx5e driver instance serving as VF representor. When SRIOV offloads mode is enabled, each VF will have a representor netdevice instance on the host. To do that, we also export set of shared service functions from en_main.c, such that they can be used by both NIC and repsresentors netdevs. The newly created representor netdevice has a basic set of net_device_ops which are the same ndo functions as the NIC netdevice and an ndo of it's own for phys port name. The profiling infrastructure allow sharing code between the NIC and the vport representor even though the representor has only a subset of the NIC functionality. The VF reps and the PF which is used in that mode to represent the uplink, expose switchdev ops. Currently the only op supposed is attr get for the port parent ID which here serves to identify net-devices belonging to the same HW E-Switch. Other than that, no offloading is implemented and hence switching functionality is achieved if one sets SW switching rules, e.g using tc, bridge or ovs. Port phys name (ndo_get_phys_port_name) is implemented to allow exporting to user-space the VF vport number and along with the switchdev port parent id (phys_switch_id) enable a udev base consistent naming scheme: SUBSYSTEM=="net", ACTION=="add", ATTR{phys_switch_id}=="<phys_switch_id>", \ ATTR{phys_port_name}!="", NAME="$PF_NIC$attr{phys_port_name}" where phys_switch_id is exposed by the PF (and VF reps) and $PF_NIC is the name of the PF netdevice.

* net/mlx5e: Add support for multiple profilesHadar Hen Zion2016-07-022-118/+240
| | | | | | | | | | | | | | | | | | | To allow support in representor netdevices where we create more than one netdevice per NIC, add profiles to the mlx5e driver. The profiling allows for creation of mlx5e instances with different characteristics. Each profile implements its own behavior using set of function pointers defined in struct mlx5e_profile. This is done to allow for avoiding complex per profix branching in the code. Currently only the profile for the conventional NIC is implemented, which is of use when a netdev is created upon pci probe. This patch doesn't add any new functionality.

* net/mlx5e: Mark enabled RQTs instances explicitlyHadar Hen Zion2016-07-023-23/+37
| | | | | | | | | | | | | | | | | | | | | In the current driver implementation two types of receive queue tables (RQTs) are in use - direct and indirect. Change the driver to mark each new created RQT (direct or indirect) as "enabled". This behaviour is needed for introducing new mlx5e instances which serve to represent SRIOV VFs. The VF representors will have only one type of RQTs (direct). An "enabled" flag is added to each RQT to allow better handling and code sharing between the representors and the nic netdevices. This patch doesn't add any new functionality.
