This is Plan 9 ipconfig(8), ported to Akaros.
ipconfig is an IP stack configuration tool. It acts as both a frontend to the filesystem-based configuration dance one does when configuring a Plan 9-derived IP stack, as well as a implementing a DHCP client and IPv6 autoconfiguration agent. It will be called from /ifconfig if present in the KFS.
Changes to Plan 9 ipconfig include reformatting the code to match Akaros kernel style, replacing alarm with Akaros system calls, removing Plan 9- and GNU-specific code and replacing with more portable idioms and general cleaning up.
