I'm also well aware that doing TCP/IP right is very very hard. It's not
possible sit down with the spec for a weekend, write up some code, and
hope it will work in the real world. That's why I didn't implement
TCP/IP. The implementation I mentioned is the unmodified NetBSD kernel
TCP/IP stack running on a very thin hypervisor layer. It's not
maintained by a few people, it's literally maintained by the entire
NetBSD community. Furthermore, it's not a set of patches available for
the NetBSD kernel updated every now and then, it's literally [in] the
kernel. It's been working this way since 2008. What I did now was just
write 200 lines of code to plug the TCP/IP stack onto DPDK.
Hopefully that convinced you that it's not just some random one-shot
kinda-works-except-in-reality bitrot attractor ;)
