Hi,
We have started to work on implementation of Zero Copy in our ETH driver based on lwip-1.4.1. But now it looks like 2.0.0 release is on it's way, so we are thinking to migrate with new development to 0.2.0.
My questions are:
- What critical changes were made between 1.4.1 and 2.0.0 in what is related to pbufs allocation/deallocation
- Are there any guidelines or thought about Zero Copy implementation in 2.0.0
Our initial effort was to find a place(s) to catch pbufs alloc/free and overlay it with our functionality that will be synced with DMA buffers creation processing and release.
I can see LWIP_SUPPORT_CUSTOM_PBUF introduced in 2.0.0. Where can we get mode details about this feature?
Thanks
