From 5180ff1364bc26c031b54a68a80aa90ce0028b70 Mon Sep 17 00:00:00 2001 From: Jan Sokolowski Date: Mon, 9 Jan 2023 15:11:18 +0100 Subject: i40e: use int for i40e_status To prepare for removal of i40e_status, change the variables from i40e_status to int. This eases the transition when values are changed to return standard int error codes over enum i40e_status. As such changes often also change variable orders, a cleanup is also applied here to make variables conform to RCT and some lines are also reformatted where applicable.
