[strongSwan] Does IKEv2 in strongSwan4.5 support ESN64bit sequence numbers by default (or does not support ESN at all)?

Extended sequence number support has been merged into Linux mainline for
2.6.39. It won't work at all if you're using an older kernel.
Our IKEv2 daemon currently negotiates 32-bit sequence numbers only, so
no support for ESN. As the kernel bits are in place now, we'll implement
userland support for ESN soon, probably for 4.5.2. It is definitely on
my TODO list.
