Subject: [RFC 0/2] Convert skb to use scatterlist
Date: Thu, 05 Jul 2007 16:14:12 -0700 [thread overview]
Message-ID: <20070705231412.021359760@linux-foundation.org> (raw)
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.
