(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 --- diff --git a/drivers/net/pasemi_mac.c b/drivers/net/pasemi_mac.c index b297a67..b2861e0 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))) {
