From 1c848a258600490f6964597b92b69a107af141d6 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Thu, 8 May 2014 22:26:32 +0100 Subject: [PATCH] net/designware: ensure device private data is DMA aligned. struct dw_eth_dev contains fields which are accessed via DMA, so make sure it is aligned to a dma boundary.
