Thanks. I request to check top-level semantics in specification header files as the first step. Other next-level details, we can change at any time. If you planning for any time frame, do let me know, so that we can decide when to start the implementation. > > > > > There was a comment to remove the TLV length.

Why not ring-pmd? Planning to emulation DWA accelerator functional model as a separate DPDK process in SW case. Therefore memif is the ideal choice as it supports zero-copy of the data as well. https://doc.dpdk.org/guides/nics/memif.html > > > c) Add drivers/dwa/sw/profiles//l3fwd - To implement l3fwd profile using > > DPDK > > libraries for SW driver. > > > > I think, Item (4) aka SW drivers as useful(We don't need to implement for > > all > > profiles, I think, just for l3fwd it make sense to add, to allow to use of > > the > > framework in just SW mode). > > Is there any opinion on adding item (4) in DPDK?
