[07/18] common/idpf: add virtchnl2 error codes
Checks
Commit Message
Virtchnl2 error codes are required for meaningful failure
information sharing between CP and PF/VF. Introduce the
necessary error codes.
New error codes were introduced removing the old ones. So
the references to the old one should be modified to avoid
CI build failures.
Use appropriate error codes wherever necessary.
