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.

util: fix possible OOB in IPv4 flowkey calc, use switch there 
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.

b9e74f34ec replace the send-to-self with a timer and an arbitrary timeout; i don't really like this but it seems to work better (1 ms is fast by human standards but an eternity for a syscall or the scheduler, so i think that's reasonable) 2019-09-24 18:28:13 -05:00

8c64e6fa09 explicitly notify the switch when a link appears to be blocked in a send instead of assuming this is the case for all idle links. how we decide when it's really blocked still needs testing/optimizing 2019-09-24 18:01:35 -05:00
