2020-01-07net/mlx5: DR, Create multiple destination action from dr_create_fteAlex Vesker1-16/+72
Until now it was possible to pass a packet to a single destination such as vport or flow table. With the new support if multiple vports or multiple tables are provided as destinations, fs_dr will create a multiple destination table action, this action should replace other destination actions provided to mlx5dr_create_rule. Each vport destination can be provided with a reformat actions which will be done before forwarding the packet to the vport.

2020-01-07net/mlx5: DR, Add support for multiple destination table actionAlex Vesker3-0/+132
A multiple destination table action allows HW packet duplication to multiple destinations, this is useful for multicast or mirroring traffic for debug. Duplicating is done using a FW flow table with multiple destinations. The new action creation function, mlx5dr_action_create_mult_dest_tbl will allow creating a single table to iterate over several dr actions.

Currently SW steering doesn't have the means to access HW iterators to support multi-destination (FTEs) flow table entries.

2020-01-07net/mlx5: Increase the max number of channels to 128Fan Li3-10/+12
Currently the max number of channels is limited to 64, which is half of the indirection table size to allow some flexibility. But on servers with more than 64 cores, users may want to utilize more queues. This patch increases the advertised max number of channels to 128 by changing the ratio between channels and indirection table slots to 1:1. At the same time, the driver still enable no more than 64 channels at loading. Users can change it by ethtool afterwards.

When APP TLV selector 1 (EtherType) is used with PID of 0, the corresponding entry specifies "default application priority [...] when application priority is not otherwise specified." mlxsw currently supports this type of APP entry, but uses it only as a fallback for unspecified DSCP rules. However non-IP traffic is prioritized according to port-default priority, not according to the DSCP-to-prio tables, and thus it's currently not possible to prioritize such traffic correctly.

Currently, VRRP packets and packets that hit exceptions during routing (e.g., MTU error) are policed using the same policer towards the CPU. This means, for example, that misconfiguration of the MTU on a routed interface can prevent VRRP packets from reaching the CPU, which in turn can cause the VRRP daemon to assume it is the Master router. Fix this by using a dedicated policer for VRRP packets.

2019-12-29mlxsw: spectrum_router: Skip loopback RIFs during MAC validationAmit Cohen1-0/+3
When a router interface (RIF) is created the MAC address of the backing netdev is verified to have the same MSBs as existing RIFs. This is required in order to avoid changing existing RIF MAC addresses that all share the same MSBs. Loopback RIFs are special in this regard as they do not have a MAC address, given they are only used to loop packets from the overlay to the underlay. Without this change, an error is returned when trying to create a RIF after the creation of a GRE tunnel that is represented by a loopback RIF. 'rif->dev->dev_addr' points to the GRE device's local IP, which does not share the same MSBs as physical interfaces. Adding an IP address to any physical interface results in: Error: mlxsw_spectrum: All router interface MAC addresses must have the same prefix. Fix this by skipping loopback RIFs during MAC validation.

2019-12-20xsk: ixgbe: i40e: ice: mlx5: Xsk_umem_discard_addr to xsk_umem_release_addrMagnus Karlsson1-1/+1
Change the name of xsk_umem_discard_addr to xsk_umem_release_addr to better reflect the new naming of the AF_XDP queue manipulation functions. As this functions is used by drivers implementing support for AF_XDP zero-copy, it requires a name change to these drivers. The function xsk_umem_release_addr_rq has also changed name in the same fashion.

2019-12-19net/mlx5e: Fix concurrency issues between config flow and XSKMaxim Mikityanskiy5-33/+13
After disabling resources necessary for XSK (the XDP program, channels, XSK queues), use synchronize_rcu to wait until the XSK wakeup function finishes, before freeing the resources. Suspend XSK wakeups during switching channels. If the XDP program is being removed, synchronize_rcu before closing the old channels to allow XSK wakeup to complete.

2019-12-18mlxsw: spectrum_qdisc: Generalize PRIO offload to support ETSPetr Machata1-23/+81
Thanks to the similarity between PRIO and ETS it is possible to simply reuse most of the code for offloading PRIO Qdisc. Extract the common functionality into separate functions, making the current PRIO handlers thin API adapters. Extend the new functions to pass quanta for individual bands, which allows configuring a subset of bands as WRR. Invoke mlxsw_sp_port_ets_set() as appropriate to de/configure WRR-ness and weight of individual bands.

With the new notifications mlxsw does not need to handle identical routes itself, as this is taken care of by the core IPv4 code.

2019-12-09mlxsw: spectrum_router: Remove unlikely user-triggerable warningIdo Schimmel1-1/+6
In case the driver vetoes the addition of an IPv6 multipath route, the IPv6 stack will emit delete notifications for the sibling routes that were already added to the FIB trie. Since these siblings are not present in hardware, a warning will be generated. Have the driver ignore notifications for routes it does not have.

2019-12-05net/mlx5e: E-switch, Fix Ingress ACL groups in switchdev mode for prio tagParav Pandit2-38/+93
In cited commit, when prio tag mode is enabled, FTE creation fails due to missing group with valid match criteria. Hence, (a) create prio tag group metadata_prio_tag_grp when prio tag is enabled with match criteria for vlan push FTE. (b) Rename metadata_grp to metadata_allmatch_grp to reflect its purpose. Also when priority tag is enabled, delete metadata settings after deleting ingress rules, which are using it. Tide up rest of the ingress config code for unnecessary labels.

2019-12-05net/mlx5e: ethtool, Fix analysis of speed settingAya Levin1-10/+3
When setting speed to 100G via ethtool (AN is set to off), only 25G*4 is configured while the user, who has an advanced HW which supports extended PTYS, expects also 50G*2 to be configured. With this patch, when extended PTYS mode is available, configure PTYS via extended fields.
