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.
