ice: Move common functions out of ice_main.c part 6/7
This patch continues the code move out of ice_main.c The following top level functions (and related dependency functions) were moved to ice_lib.c: ice_vsi_setup_vector_base ice_vsi_alloc_q_vectors ice_vsi_get_qs The following functions were made static again: ice_vsi_free_arrays ice_vsi_clear_rings Also, in this patch, the netdev and NAPI registration logic was de-coupled from the VSI creation logic (ice_vsi_setup) as for SR-IOV, while we want to create VF VSIs using ice_vsi_setup, we don't want to create netdevs. Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
