Hi Mr. Horman Could you take a look at the mail? I noticed you are working on layer 3 port now, what's your opinion on my requirement?
I am thinking of implementing it especially for OVS running under DPDK context, could you give me some advice?

But in OVS, I don't know if there is another way except for inserting a flow rule that has mac addresses of 10.1.1.1 and 10.1.1.10 and using such actions as mod_dl_src and mod_dl_dst What I am asking for is adding a layer 3 port, which has some ability similar with current tunnel port, and such layer 3 port can query route cache which OVS maintained for tunnel, and neigh tables, w/o asking for kernel (especially it runs in DPDK context). Such layer 3 port is not tunnel port so its behavior only relies on forwarding and modifying l2 headers I've searched previous mails and there is indeed some work on layer 3 port, but such port doesn't have all I asked above. I am wondering if there is a plan on this in future OVS roadmap, What you maintainer guys think about the requirement I proposed. I am yearning for your advices, and maybe I can contribute to such things if you think it is worth of doing. Correct me if anything wrong, thank you.
