The subsequent unconditional call\nto ice_vf_post_vsi_rebuild() leads to a NULL pointer dereference in\nice_ena_vf_q_mappings() when it accesses vsi->txq_map[0].\n\nThe single-VF reset path in ice_reset_vf() already handles this\ncorrectly by checking the return value of ice_vf_reconfig_vsi() and\nskipping ice_vf_post_vsi_rebuild() on failure.\n\nApply the same pattern to ice_reset_all_vfs(): check the return value\nof ice_vf_rebuild_vsi() and skip ice_vf_post_vsi_rebuild() and\nice_eswitch_attach_vf() on failure.
