Subject: [PATCH 1/1] make network DMA usable for non-tcp drivers

Here is a patch against the netdev-2.6 git tree that makes the net DMA
feature usable for drivers like the ATA over Ethernet block driver,
which can use dma_skb_copy_datagram_iovec when receiving data from the
network.

The change was suggested on kernelnewbies.
