bnx2: remove skb_dma_map/unmap calls from driver
Due to the fact that skb_dma_map/unmap do not work correctly when a HW
IOMMU is enabled it has been recommended to go about removing the calls
from the network device drivers.
[ Fix bnx2_free_tx_skbs() ring indexing and use NETDEV_TX_OK return
code in bnx2_start_xmit() after cleaning up DMA mapping errors. -Mchan ]
