Topic: help compiling multipath-tcp into kernel on 15.05.1

The content of this topic has been archived on 17 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

i've followed the guide posted here:

http://mytechpg.blogspot.it/2016/01/mul … enwrt.html

but after I boot openwrt-ar71xx-generic-archer-c7-v2-squashfs-factory.bin

I get the following:

root@OpenWrt:~# multipath
Your device don't support multipath-TCP.
You have to install the pached kernel to use MPTCP.
See http://multipath-tcp.org/ for details
root@OpenWrt:/# dmesg | grep MPTCP
root@OpenWrt:/#

after I issue the final 'make' command, the .config file in:

openwrt/build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.18.29/

does not have my kernel configuration changes in it, but the other files do:

.config.old       .config.override  .config.target

is there a reason why the resultant .config doesnt have my edits, or is there a better way to figure out why it's not using my .config.target?

The build shows no errors or warnings and finishes

turns out MPTCP relies on IPV6 in-kernel, but selecting MPTCP doesnt enable IPv6 automatically.

So turning on IPv6 solved this problem.
