Greetings,

Hope you all are doing well!

My question is regarding the following log. Could anyone suggest a possible
solution for the following log?

  i40evf_disable_vlan_strip(): Failed to execute command of
  VIRTCHNL_OP_DISABLE_VLAN_STRIPPING

It looks you disabled vlan stripping, the error says vf command opcode
VIRTCHNL_OP_DISABLE_VLAN_STRIPPING to PF received no response.

Fail to configure VSI queues

maybe check your DPDK setting in guest and PF setting in host? again I am
not DPDK driver expert :)
