From 68cdf5d6e91068c98d6091b193dc7a5ab7dcf5eb Mon Sep 17 00:00:00 2001 From: Achiad Shochat Date: Wed, 29 Jul 2015 15:05:40 +0300 Subject: [PATCH] net/mlx5e: Use hard-coded 4K page size for RQ/SQ/CQ The page size of the device's RQ/SQ/CQ objects is defined in 4K units regardless of the system pages size. Thus using the Linux's PAGE_SHIFT macro yields wrong device configuration in systems where PAGE_SHIFT!=12. Signed-off-by: Achiad Shochat Signed-off-by: Amir Vadai Signed-off-by: David S.
