A Zero-copy ethernet solution would be indeed a great addition, when implementing a enet driver myself I noticed as well that packets are double stored and have a unnecessary copy action, furthermore hw TCP/IP offloading (HW checksum etc) is also thing NuttX doesn't support that well. But wouldn't it be better to come up with a proposal to offload DMA directly into a IOB buffer and start a discussion (i.e. NuttX mailing list) how we can make this portable in such a way that it works all kinds of ethernet MAC's that have build-in DMA. I think this requires more changes into how IOB works but also the API of the NuttX Networking to work with these changes. -- This is an automated message from the Apache Git Service.
