net/mlx5: Support extended destination format in flow steering command

2018-12-10T22:00:08+00:00

Update the flow steering command formatting according to the extended
destination API.
Note that the FW dictates that multi destination FTEs that involve at
least one encap must use the extended destination format, while single
destination ones must use the legacy format.
Using extended destination format requires FW support. Check for its
capabilities and return error if not supported.

net/mlx5: E-Switch, Change vhca id valid bool field to bit flag

2018-12-10T22:00:08+00:00

Change the driver flow destination struct to use bit flags with the vhca
id valid being the 1st one. The flags field is more extendable and will
be used in downstream patch.

net/mlx5: Add a no-append flow insertion mode

2018-10-17T21:18:50+00:00

If no-append flag is set, we will add a new FTE, instead of appending
the actions of the inserted rule when the same match already exists.

While here, move the has_flow_tag boolean indicator to be a flag too.

This patch doesn't change any functionality.

net/mlx5: Split FDB fast path prio to multiple namespaces

2018-10-17T21:18:16+00:00

Towards supporting multi-chains and priorities, split the FDB fast path
to multiple namespaces (sub namespaces), each with multiple priorities.

This patch adds a new flow steering type, FS_TYPE_PRIO_CHAINS, which is
like current FS_TYPE_PRIO, but may contain only namespaces, and those
will be in parallel to one another in terms of managing of the flow
tables connections inside them. Meaning, while searching for the next
or previous flow table to connect for a new table inside such namespace
we skip the parallel namespaces in the same level under the
FS_TYPE_PRIO_CHAINS prio we originated from.

We use this new type for splitting the fast path prio into multiple
parallel namespaces, each containing normal prios.
The prios inside them (and their tables) will be connected to one
another, but not from one parallel namespace to another, instead the
last prio in each namespace will be connected to the next prio in
the containing FDB namespace, which is the slow path prio.

net/mlx5: Use flow counter IDs and not the wrapping cache object

2018-10-17T21:15:48+00:00

Currently, when a flow rule is created using the FS core layer, the caller
has to pass the entire flow counter object and not just the counter HW
handle (ID). This requires both the FS core and the caller to have
knowledge about the inner implementation of the FS layer flow counters
cache and limits the possible users.

Move to use the counter ID across the place when dealing with flows.

Doing this decoupling, now can we privatize the inner implementation
of the flow counters.

net/mlx5: E-Switch, Get counters for offloaded flows from callers

2018-10-17T21:15:48+00:00

There's no real reason for the e-switch logic to manage the creation of
counters for offloaded flows. The API already has the directive for the
caller to denote they want to attach a counter to the created flow.
As such, we go and move the management of flow counters to the mlx5e
tc offload logic. This also lets us remove an inelegant interface where
the FS layer had to provide a way to retrieve a counter from a flow rule.

{net, RDMA}/mlx5: Rename encap to reformat packet

2018-09-05T05:10:59+00:00

Renames all encap mlx5_{core,ib} code to use the new naming of packet
reformat. This change doesn't introduce any function change and is
needed to properly reflect the operation being done by this action.
For example not only can we encapsulate a packet, but also decapsulate it.

net/mlx5: Break encap/decap into two separated flow table creation flags

2018-09-05T04:58:00+00:00

Today we are able to attach encap and decap actions only to the FDB. In
preparation to enable those actions on the NIC flow tables, break the
single flag into two. Those flags control whatever a decap or encap
operations can be attached to the flow table created. For FDB, if
encapsulation is required, we set both of them.
