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.
