To support configurable CRC stripping in VF, a new
operation of I40E_VIRTCHNL_OP_CONFIG_VSI_QUEUES_EX
is added to carry more configuration information from
VM to Intel(r) DPDK PF host, comparing to
I40E_VIRTCHNL_OP_CONFIG_VSI_QUEUES which is supported
by Linux PF host.

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.

To support configurable CRC in VF, use operation of
I40E_VIRTCHNL_OP_CONFIG_VSI_QUEUES_EX to carry more
information from VM to PF host, if the peer is DPDK
PF host. Otherwise assume it is Linux PF host and
just use operation of I40E_VIRTCHNL_OP_CONFIG_VSI_QUEUES.

As i40e support configurable CRC stripping in VF,
the useless configuration of
CONFIG_RTE_LIBRTE_I40E_PF_DISABLE_STRIP_CRC should
be removed.

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).

It's not clear why you reworked the legacy function.
Please explain it in the commit log and move renamings in a separated patch.
