charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: intel-wired-lan-bounces@osuosl.org Sender: "Intel-wired-lan" The .back field placed in i40e_hw is used to get pointer to i40e_pf instance but it is not necessary as the i40e_hw is a part of i40e_pf and containerof macro can be used to obtain the pointer to i40e_pf. Remove .back field from i40e_hw structure, introduce i40e_hw_to_pf() and i40e_hw_to_dev() helpers and use them.
