From 71d28725548be203e8b8f6ad63b1f64fd7f02d4d Mon Sep 17 00:00:00 2001 From: Dale Farnsworth Date: Wed, 13 Sep 2006 09:21:08 -0700 Subject: [PATCH] [PATCH] mv643xx_eth: Unmap DMA buffers in receive path Fix a missing call to dma_unmap_single() in the receive path. Without this call, errors have been observed on non-cache-coherent systems.
