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.
