> This patch fixes the warning messages/call traces seen if DMA debug is
> enabled, In case of fragmented skb's memory was allocated using
> dma_map_page but freed using dma_unmap_single. This patch modifies buffer
> allocations in TX path to use dma_map_page in all the places and
> dma_unmap_page while freeing the buffers.
