mlx5-updates-2018-10-17 ...
========================================================================
From Or Gerlitz <ogerlitz@mellanox.com>:
This series from Paul adds support to mlx5 e-switch tc offloading of multiple priorities and chains.
This is made of four building blocks (along with few minor driver refactors):
[1] Split FDB fast path prio to multiple namespaces
Currently the FDB name-space contains two priorities, fast path (p0) and slow path (p1).
The slow path contains the per representor SQ send-to-vport TX rule and the match-all
RX miss rule. As a pre-step to support multi-chains and priorities, we split the FDB fast path
to multiple namespaces (sub namespaces), each with multiple priorities.
[2] E-Switch chains and priorities
A chain is a group of priorities. We use the fdb parallel sub-namespaces to implement chains,
and a flow table for each priority in them.
Because these namespaces are parallel and in series to the slow path
fdb, the chains aren't connected to each other (but to the slow path),
and one must use a explicit goto action to reach a different chain.
Flow tables for the priorities are created on demand and destroyed
once not used.
[3] Add a no-append flow insertion mode, use it for TC offloads
Enhance the driver fs core, such that if a no-append flag is set by the caller,
we add a new FTE, instead of appending the actions of the inserted rule when
the same match already exists.
For encap rules, we defer the HW offloading till we have a valid neighbor. This can
result in the packet hitting a lower priority rule in the HW DP. Use the no-append API
to push these packets to the slow path FDB table, so they go to the TC kernel DP as done
before priorities where supported.
[4] Offloading tc priorities and chains for eswitch flows
Using [1], [2] and [3] above we add the support for offloading both chains
and priorities. To get to a new chain, use the tc goto action. We support
a fixed prio range 1-16, and chains 0-3.
