From ada68c31ba9c02d7aabdd87db979fe670b499d54 Mon Sep 17 00:00:00 2001 From: Achiad Shochat Date: Mon, 22 Feb 2016 18:17:23 +0200 Subject: net/mlx5: Introduce a new header file for physical port functions All the device physical port access functions are implemented in the port.c file. We just extract the exposure of these functions from driver.h into a dedicated header file called port.h. Signed-off-by: Achiad Shochat Signed-off-by: Saeed Mahameed Signed-off-by: David S.

The code before this fix tries to map it both to WC and NC contrary to what stated in Intel's software developer manual. Here we remove the global WC mapping of all UARS "dev->priv.bf_mapping", since UAR mapping should be decided per UAR (e.g we want different mappings for EQs, CQs vs QPs). Caller will now have to choose whether to map via write-combining API or not. mlx5e SQs will choose write-combining in order to perform BlueFlame writes.
