net/mlx5: Use underlay QPN from the root name space

2017-05-14T10:33:45Z

Root flow table is dynamically changed by the underlying flow steering layer, and IPoIB/ULPs have no idea what will be the root flow table in the future, hence we need a dynamic infrastructure to move Underlay QPs with the root flow table.

net/mlx5: Refactor create flow table method to accept underlay QP

2017-04-17T15:08:29Z

IB flow tables need the underlay qp to perform flow steering. Here we change the API of the flow tables creation to accept the underlay QP number as a parameter in order to support IB (IPoIB) flow steering. Signed-off-by: Erez Shitrit Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

net/mlx5: Introduce modify header structures, commands and steering action definitions

2017-03-28T12:34:04Z

Add the definitions related to creation/deletion of a modify header context and the modify header steering action which are used for HW packet header modify (re-write) as part of steering. Add as well the modify header id into two intermediate structs and set it to the FTE. Note that as the push/pop vlan steering actions are emulated by the ewitch management code, we're not breaking any compatibility while changing their values to make room for the modify header action which is not emulated and whose value is part of the FW API. The new bit values for the emulated actions are at the end of the possible range. Signed-off-by: Or Gerlitz Reviewed-by: Hadar Hen Zion Signed-off-by: Saeed Mahameed

net/mlx5: Add helper to initialize a flow steering actions struct instance

2017-03-28T12:34:01Z

There are bunch of places in the code where the intermediate struct that keeps the elements related to flow actions is initialized with the same default values. Put that into a small DECLARE type helper. This patch doesn't change any functionality. Signed-off-by: Or Gerlitz Reviewed-by: Hadar Hen Zion Signed-off-by: Saeed Mahameed

net/mlx5: Support encap id when setting new steering entry

2016-11-09T18:41:56Z

In order to support steering rules which add encapsulation headers, encap_id parameter is needed. Add new mlx5_flow_act struct which holds action related parameter: action, flow_tag and encap_id. Use mlx5_flow_act struct when adding a new steering rule. This patch doesn't change any functionality. Signed-off-by: Hadar Hen Zion Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

net/mlx5: Add creation flags when adding new flow table

2016-11-09T18:41:56Z

When creating flow tables, allow the caller to specify creation flags. Currently no flags are used and as such this patch doesn't add any new functionality. Signed-off-by: Hadar Hen Zion Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

net/mlx5: Add multi dest support

2016-10-30T13:43:17Z

Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler).

net/mlx5: Add sniffer namespaces

2016-08-18T15:49:59Z

Add sniffer TX and RX namespaces to receive ingoing and outgoing traffic. Each outgoing/incoming packet is duplicated and steered to the sniffer TX/RX namespace in addition to the regular flow. Signed-off-by: Maor Gottlieb Signed-off-by: Saeed Mahameed Signed-off-by: Leon Romanovsky

net/mlx5: Add LAG flow steering namespace

2016-08-18T15:49:57Z

This namespace is used for LAG demux flowtable. The idea is to position the LAG demux ft between bypass and kernel flowtables, allowing raw-eth traffic from both ports to be received by the PF0 IB device.

net/mlx5: LAG demux flow table support

2016-08-18T15:49:56Z

Add interfaces to allow the creation and destruction of a LAG demux flow table. It is a special flow table used during LAG for redirecting non user-mode packets from PF0 to PF1 root ft, if a packet was received on phys port two.
