Unaligned access caused SIGBUS errors on ARMv6 and ARMv7 targets under FreeBSD. This was also the cause of the repeating TAP devices. Each time the SIGBUS happened, the service would auto-restart itself, create a new TAP device, and then crash again. The particular place causing the SIGBUS was: https://github.com/zerotier/ZeroTierOne/blob/master/node/Utils.hpp#L695
