[dpdk-dev] [PATCH v4 0/7] add Intel DCF PMD support

A DCF (Device Config Function) based approach is proposed where a device
bound to the device's VF0 can act as a sole controlling entity to exercise
advance functionality (such as switch, ACL) for rest of the VFs.

The DCF works as a standalone PMD to support this function, which shares the
ice PMD flow control core function and the iavf virtchnl mailbox core module.

v4:
   Change the alarm handler to thread service, since it will need to do more
   work.

v3:
   1. Fixed the error log message format.
   2. Fixed some memory allocation check.
   3. Fixed some code style issue and commmit message description.

v2: 
   1. update the iavf patchset link.
   2. split more patches for making this work be more understandable
   3. fix the log function usage, devargs checking from v1.

Haiyue Wang (7):
  net/iavf: stop the PCI probe in DCF mode
  net/ice: add the DCF hardware initialization
  net/ice: acquire and disable the DCF capability
  net/ice: handle the AdminQ command by DCF
  net/ice: export the DDP definition symbols
  net/ice: handle the PF initialization by DCF
  net/ice: get the VF hardware index in DCF
