Subject: [dpdk-dev] [PATCH 2/2] ethdev: tunnel offload model
Date: Thu, 25 Jun 2020 19:03:48 +0300
Message-ID: <20200625160348.26220-3-getelson@mellanox.com> (raw)

Hardware vendors implement tunneled traffic offload techniques
differently. Although RTE flow API provides tools capable to offload
all sorts of network stacks, software application must reference this
hardware differences in flow rules compilation. As the result tunneled
traffic flow rules that utilize hardware capabilities can be different
for the same traffic.

Tunnel port offload proposed in [1] provides software application with
unified rules model for tunneled traffic regardless underlying
hardware.
 - The model introduces a concept of a virtual tunnel port (VTP).
 - The model uses VTP to offload ingress tunneled network traffic 
   with RTE flow rules.
 - The model is implemented as set of helper functions. Each PMD
   implements VTP offload according to underlying hardware offload
   capabilities.  Applications must query PMD for VTP flow
   items / actions before using in creation of a VTP flow rule.

The model components:
- Virtual Tunnel Port (VTP) is a stateless software object that
  describes tunneled network traffic.  VTP object usually contains
  descriptions of outer headers, tunnel headers and inner headers.
- Tunnel Steering flow Rule (TSR) detects tunneled packets and
  delegates them to tunnel processing infrastructure, implemented
  in PMD for optimal hardware utilization, for further processing.
- Tunnel Matching flow Rule (TMR) verifies packet configuration and
  runs offload actions in case of a match.

Application actions:
1 Initialize VTP object according to tunnel
  network parameters.
2 Create TSR flow rule:
2.1 Query PMD for VTP actions: application can query for VTP actions
    more than once
    int
    rte_flow_tunnel_decap_set(uint16_t port_id,
                              struct rte_flow_tunnel *tunnel,
                              struct rte_flow_action **pmd_actions,
                              uint32_t *num_of_pmd_actions,
                              struct rte_flow_error *error);

2.2 Integrate PMD actions into TSR actions list.
2.3 Create TSR flow rule:
    flow create <port> group 0
          match {tunnel items} / end
          actions {PMD actions} / {App actions} / end

3 Create TMR flow rule:
3.1 Query PMD for VTP items: application can query for VTP items
    more than once
    int
    rte_flow_tunnel_match(uint16_t port_id,
                          struct rte_flow_tunnel *tunnel,
                          struct rte_flow_item **pmd_items,
                          uint32_t *num_of_pmd_items,
                          struct rte_flow_error *error);

3.2 Integrate PMD items into TMR items list:
3.3 Create TMR flow rule
    flow create <port> group 0
          match {PMD items} / {APP items} / end
          actions {offload actions} / end

The model provides helper function call to restore packets that miss
tunnel TMR rules to its original state:
int
rte_flow_get_restore_info(uint16_t port_id,
                          struct rte_mbuf *mbuf,
                          struct rte_flow_restore_info *info,
                          struct rte_flow_error *error);

rte_tunnel object filled by the call inside
rte_flow_restore_info *info parameter can be used by the application
to create new TMR rule for that tunnel.

The model requirements:
Software application must initialize
rte_tunnel object with tunnel parameters before calling
rte_flow_tunnel_decap_set() & rte_flow_tunnel_match().

PMD actions array obtained in rte_flow_tunnel_decap_set() must be
released by application with rte_flow_action_release() call.
Application can release the actionsfter TSR rule was created.

PMD items array obtained with rte_flow_tunnel_match() must be released
by application with rte_flow_item_release() call.  Application can
release the items after rule was created. However, if the application
needs to create additional TMR rule for the same tunnel it will need
to obtain PMD items again.

Application cannot destroy rte_tunnel object before it releases all
PMD actions & PMD items referencing that tunnel.
