> This patch implements parts of ice_sriov_configure and VF reset flow.
> 
> To create virtual functions (VFs), the user sets a value in num_vfs through
> sysfs. This results in the kernel calling the handler for .sriov_configure which
> is ice_sriov_configure.
> 
> VF setup first starts with a VF reset, followed by allocation of the VF VSI using
> ice_vf_vsi_setup. Once the VF setup is complete a state bit
> ICE_VF_STATE_INIT is set in the vf->states bitmap to indicate that the VF is
> ready to go.
> 
> Also for VF reset to go into effect, it's necessary to issue a disable queue
> command (ice_aqc_opc_dis_txqs). So this patch updates multiple functions
> in the disable queue flow to take additional parameters that distinguish if
> queues are being disabled due to VF reset.
