Subject: Fwd: dma_skb_copy_datagram_iovec not EXPORTed
Hello,
I'm forwarding along a message sent to kernelnewbies as I was directed
to address my question to this list. I am not a member of netdev, so
please copy me on all discussion of this topic.
Cheers,

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.
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
