Subject: net/iavf: fix mismatch command
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b343b6eefd9d281d1adffe701407c59a4f74b1f9;p=dpdk.git

net/iavf: fix mismatch command

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")
