Message-ID: <20070608143053.GC10489@coraid.com> Date: Fri, 8 Jun 2007 10:30:53 -0400 From: "Ed L. Cashin" <ecashin@...aid.com> To: netdev@...r.kernel.org Cc: s.a.hopkins@...il.com, jgarzik@...ox.com, randy.dunlap@...cle.com, akpm@...ux-foundation.org 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. http://article.gmane.org/gmane.linux.kernel.kernelnewbies/21663 Signed-off-by: Ed L.
