Ubuntu 16.04 and 18.04 have xl2tpd packages with backported patch to workaround this kernel issue are now in their respective updates repositories:

18.04 (bionic) - xl2tpd 1.3.10-1ubuntu1
16.04 (xenial) - xl2tpd 1.3.6+dfsg-4ubuntu0.16.04.2

A previous workaround was to build xl2tpd from source code :

sudo apt install build-essential git libpcap0.8-dev
sudo systemctl stop xl2tpd
git clone https://github.com/xelerance/xl2tpd.git
cd xl2tpd
make
sudo cp xl2tpd /usr/sbin/xl2tpd
