3 years agocommon/iavf: support new VLAN capabilities
Qi Zhang [Thu, 7 Jan 2021 05:07:08 +0000 (13:07 +0800)]
common/iavf: support new VLAN capabilities

Currently VIRTCHNL only allows for VLAN filtering and offloads to happen
on a single 802.1Q VLAN. Add support to filter and offload on inner,
outer, and/or inner + outer VLANs.

This is done by introducing the new capability
VIRTCHNL_VF_OFFLOAD_VLAN_V2. The flow to negotiate this new capability
is shown below.

1. VF - sets the VIRTCHNL_VF_OFFLOAD_VLAN_V2 bit in the
   virtchnl_vf_resource.vf_caps_flags during the
   VIRTCHNL_OP_GET_VF_RESOURCES request message. The VF should also set
   the VIRTCHNL_VF_OFFLOAD_VLAN bit in case the PF driver doesn't
   support the new capability.

2. PF - sets the VLAN capability bit it supports in the
   VIRTCHNL_OP_GET_VF_RESOURCES response message. This will either be
   VIRTCHNL_VF_OFFLOAD_VLAN_V2, VIRTCHNL_VF_OFFLOAD_VLAN, or none.

3. VF - If the VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability was ACK'd by the
   PF, then the VF needs to request the VLAN capabilities of the
   PF/Device by issuing a VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS request.
   If the VIRTCHNL_VF_OFFLOAD_VLAN capability was ACK'd then the VF
   knows only single 802.1Q VLAN filtering/offloads are supported. If no
   VLAN capability is ACK'd then the PF/Device doesn't support hardware
   VLAN filtering/offloads for this VF.

4. PF - Populates the virtchnl_vlan_caps structure based on what it
   allows/supports for that VF and sends that response via
   VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS.

After VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS is successfully negotiated
the VF driver needs to interpret the capabilities supported by the
underlying PF/Device. The VF will be allowed to filter/offload the
inner 802.1Q, outer (various ethertype), inner 802.1Q + outer
(various ethertypes), or none based on which fields are set.

The VF will also need to interpret where the VLAN tag should be inserted
and/or stripped based on the negotiated capabilities.

Also, update the virtchnl_op_str() function to support the added opcodes.

Async enqueue offloads large copies to DMA devices, and small copies
are still performed by the CPU. However, it requires users to get
enqueue completed packets by rte_vhost_poll_enqueue_completed(), even
if they are completed by the CPU when rte_vhost_submit_enqueue_burst()
returns. This design incurs extra overheads of tracking completed
pktmbufs and function calls, thus degrading performance on small packets.

This patch enhances async enqueue for small packets by enabling
rte_vhost_submit_enqueue_burst() to return completed packets.
