From 18eec695427ce1258fb5dad0ac180fa4d6f64af7 Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Tue, 2 Oct 2007 16:25:14 -0500 Subject: [PATCH] pasemi_mac: fix bug in receive buffer dma mapping pasemi_mac: fix bug in receive buffer dma mapping skb->len isn't actually set to the size of the allocated skb, so don't try to use it when figuring out how much to map. (This hasn't surfaced as a real bug because we effectively disable translation for the interface, but it still needs fixing for the future) Signed-off-by: Olof Johansson Signed-off-by: Jeff Garzik --- drivers/net/pasemi_mac.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/pasemi_mac.c b/drivers/net/pasemi_mac.c index b297a67d2fb..b2861e0df86 100644 --- a/drivers/net/pasemi_mac.c +++ b/drivers/net/pasemi_mac.c @@ -396,7 +396,7 @@ static void pasemi_mac_replenish_rx_ring(struct net_device *dev, int limit) if (unlikely(!skb)) break; - dma = pci_map_single(mac->dma_pdev, skb->data, skb->len, + dma = pci_map_single(mac->dma_pdev, skb->data, BUF_SIZE, PCI_DMA_FROMDEVICE); if (unlikely(dma_mapping_error(dma))) { -- 2.20.1
