net/iavf: fix mismatch command
Checks
Commit Message
The "command mismatch" warning shouldn't be triggered by
VIRTCHNL_OP_EVENT opcode, because the VIRTCHNL_OP_EVENT
opcode is used by PF notifies status change events to VF.
This patch fixed the issue.
Fixes: 837c2ed86e4c ("net/iavf: return error if opcode is mismatched")
