Cover letter [RFC 0/2] Convert skb to use scatterlist

This topic came up at first Netconf. This patch changes skbuff to use scatterlist. Why? Devices can than use the pci_dma_sg routines to map the fraglist in one operation. This allows for better error handling (less unwinding), and some IOMMU's (PPC?) can be smarter.
