Custom network stack in Go
This networkstack implements (very) basic and rudimentary support for connecting tcp streams. There needs to be a lot to be implemented and optimised.
Currently netstack is being used by the following projects:
Linux will send RST packets for unknown tcp packets, so this needs to be disabled using iptables.
iptables -A OUTPUT -p tcp --tcp-flags RST RST -j DROP
iptables -I OUTPUT -p icmp --icmp-type destination-unreachable -j DROP
