Hi Aruna Thanks a lot! I changed the Kconfig to tristate and set the config_INET=m. I also needed to add "depends on CONFIG_INET" to other config options those depend on INET. I could build it. But when I reboot, I got the following error and it doesn't boot. Giving up :-( error getting socket: Address family not supported by protocol error initializing udev control socket I'm trying to write a Media-friendly TCP (by implementing a new option). Please let me know if you have any suggestion.
