From e281682bf29438848daac11627216bceb1507b71 Mon Sep 17 00:00:00 2001 From: Saeed Mahameed Date: Thu, 28 May 2015 22:28:40 +0300 Subject: net/mlx5_core: HW data structs/types definitions cleanup mlx5_ifc.h was heavily modified here since it is now generated by a script from the device specification (PRM rev 0.25). This specification is backward compatible to existing hardware. Some structures/fields were added here in order to enable the Ethernet functionality of the driver.
