As Yuanhan said, there are many TCP stacks running on top of DPDK.
We should add this one to the list:
	https://www.dpdk.org/ecosystem/#projects
Also a discussion has started recently about integrating one in DPDK.
As Jerin suggests, libtpa looks like a very good candidate to focus efforts on it.

Regarding performance, how does it compare with F-Stack? TLDK? Seastar?
