Re: [dpdk-dev] [PATCH 0/2] examples/vhost: support new VMDQ api and new nic i40e in vhost example

["Fu, JingguoX" <jingguox.fu@intel.com>]

As we validate dpdk 1.8.0 rc2 from org, we report defect: Work_Request  IXA00388707
The defect is about vhost virtio based 4 x 10 G NIC, and vhost-switch cannot startup, all cases for one copy on Fortville cannot validate. This defect can be fixed by this patches. Below are details for validation.

Subject: [dpdk-dev] [PATCH 0/2] examples/vhost: support new VMDQ api and new nic i40e in vhost example

I40E has several different types of VSI and queues are allocated among them. VMDQ queue base and pool base doesn't start from zero due to this change and VMDQ doesn't own all queues.
rte_eth_dev_info structure is extended to provide VMDQ queue base, pool base, queue number information for us to properly set up VMDQ, i.e, add mac/vlan filter.
This patchset enables the vhost example to use this information to set up VMDQ.

Huawei Xie (2):
  support new VMDQ API and new nic i40e
  use factorized default Rx/Tx configuration
