From 8062b2263a9fc294ddeb4024b113e8e26b82d5de Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Fri, 14 Sep 2018 17:37:44 -0700 Subject: intel-ethernet: rename i40evf to iavf Rename the Intel Ethernet Adaptive Virtual Function driver (i40evf) to a new name (iavf) that is more consistent with the ongoing maintenance of the driver as the universal VF driver for multiple product lines. This first patch fixes up the directory names and the .ko name, intentionally ignoring the function names inside the driver for now. Basically this is the simplest patch that gets the rename done and will be followed by other patches that rename the internal functions. This patch also addresses a couple of string/name issues and updates the Copyright year. Also, made sure to add a MODULE_ALIAS to the old name.

Most of the changes were made mechanically, which introduces some alignment issues.

A future patch will remove the i40e references (after the code removal patches later in this series).

Some of the adminq code, as well as most of the client interface code used by RDMA is left unchanged in order to indicate that the driver is talking to non-internal to iavf code.
