1daf3e7bd7 remove link.go block on oldIntf if we already have a connection to the same node, this spams connections, so it's not a good long-term fix if that's where the goroutine leak is 2020-12-13 16:16:14 -06:00

Change DefaultIfName from "/dev/tun0" to "tun0"
Specifying the full path to the interface in OpenBSD would result in:
panic: Interface name must be tun[0-9]*

Therefore, DefaultIfName should be changed to tun0 in order to make yggdrasil work out of the box.

8358fe5c5c Unify MTU datatypes across the codebase
The codebase uses int and unit16 to represent MTU randomly. This change
unifies it to a MTU type from types package, which is currently uint16.

ihl may grow upto 15*4=60 so extract and check it before using it as offset in flowkey calculation.
also replace IFs with switches for protocol matching as it's less redundant and nicer to document.
