From 37b545f00f84de7544744792a246cd9ae7917675 Mon Sep 17 00:00:00 2001 From: juhosg Date: Wed, 24 Nov 2010 10:01:16 +0000 Subject: ramips: DMA map the correct RX skb size The skb_reserve call prior to DMA mapping the RX skb reduced the skb data len by 2. To not allow DMA to write behind the skb we should pass the correct skb data len to the device.
