Hello list,

I just tried to use esn (extended sequence numbers), but the responder got that error:

Dez 15 22:32:43 thermi.strangled.net charon-systemd[1105]: parsed CREATE_CHILD_SA request 2 [ N(IPCOMP_SUP) SA No KE TSi TSr ]

`uname -a`
Linux thermi.strangled.net 3.14.25-1-lts #1 SMP Fri Nov 21 19:41:09 UTC 2014 x86_64 GNU/Linux

The distribution is Arch Linux and it's the second newest lts kernel the distro has.

On what kernel feature does esn depend? Is there an extra module for it?
