[dpdk-dev,1/3] i40evf: support I40E_VIRTCHNL_OP_CONFIG_VSI_QUEUES_EX in DPDK PF host
Commit Message
To configure VSI queues for VF, Linux PF host supports
operation of I40E_VIRTCHNL_OP_CONFIG_VSI_QUEUES with
limited configurations. To support more configurations
(e.g configurable CRC stripping in VF), a new operation
of I40E_VIRTCHNL_OP_CONFIG_VSI_QUEUES_EX has been
supported in DPDK PF host.

Hi Helin,
The title mention i40evf but the patch is related to PF (for VF communication).
So I wonder wether it would be clearer to prefix it with i40e? Not sure.

This patch would be easier to read if you could split it in 3 patches:
1) renamings and line wrapping rework
2) introduction of new extended message/operation
3) crc config

Mixing renaming and new feature makes it difficult to read.

Line wrapping should go in a cleanup patch (like renaming).

Thank you very much! I have reworked the patches and sent out again.
