Greetings, I am a developer of the kernel AoE (ATA over Ethernet) driver. I am attempting to add dma offloading of data receive, following in TCP's footsteps via config option NET_DMA. There is a function in net/core/user_dma.c, dma_skb_copy_datagram_iovec, that appears to be exactly what I need, but this function is not EXPORTed for use by external modules. Does anyone know why? Since the NET_DMA option is documented as "Network: TCP receive copy offload" perhaps it's just an oversight that anyone else might benefit from it? Cheers, Sam
Sam, I think the general rule is not to export functions until there is an actual user. I would put together a quick patch with your description above to export it and send it straight to netdev@xxxxxxxxxxxxxxxx FYI: I assume you know Jeff Garzik is the maintainer of both a lot of network drivers and the libata implementation of ATA. He should be monitoring netdev, and I know he is on linux-ide all the time. Also, I think he hangs out on a IRC somewhere, but I don't know where.
