From 3d16af8665504c89f9ef3aae56f54fb93e48da61 Mon Sep 17 00:00:00 2001 From: Benjamin Li Date: Thu, 9 Oct 2008 12:26:41 -0700 Subject: bnx2: Handle DMA mapping errors. Before, the driver would not care about the return codes from pci_map_* functions. This could be potentially dangerous if a mapping failed. Now, we will check all pci_map_* calls. On the transmit side, we switch to use the new function skb_dma_map(). On the receive side, we add pci_dma_mapping_error().
