2016-11-04 17:10, Qiming Yang:
> If VF device is used as slave of a bond device, it will be polled
> periodically through alarm. Interrupt is involved here. And then
> VF will send I40E_VIRTCHNL_OP_GET_LINK_STAT message to
> PF to query the status. The response is handled by interrupt
> callback. Interrupt is involved here again. That's why bond
> device cannot bring up.
>
> This patch removes I40E_VIRTCHNL_OP_GET_LINK_STAT
> message. Link status in VF driver will be updated when PF driver
> notify it, and VF stores this link status locally. VF driver just
> returns the local status when being required.
