hack 4.14 support for kernel 4.14.221

[mfoxworthy]

I have tried to patch the kernel 4.14.221 with the hack that is using 4.14.174 and, as you may have expected, several chunks fail.

It doesn't appear to have many differences between 221 and 174 it's just that I'm not experienced enough in the kernel networking to be messing around in there.

I have considered moving to a supported kernel but the devices I am using, GL.iNet devices have features for the Goodcloud management system that I am using. I am basically stuck with Openwrt 19.07.7 for now and likely for a while.

Here is the output of the patch failure:

I don't maintain 4.14 kernel any more.
You can try to make an updated patch from https://github.com/multipath-tcp/mptcp/tree/mptcp_v0.94

[mfoxworthy]

I noticed that you have told others the same. I figured that would be the answer, but it was worth asking anyway. :)

I'll try patching it myself.

Thanks.
