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
691192ff5a weird scheduler hack, seems to tend to make things more stable without actually locking streams to any particular link 2019-09-21 14:33:45 -05:00
87658f83e9 Revert "force things to buffer in the switch if the best link is currently busy. note that other links can end up sending if they become non-idle for other reasons. this is a temporary workaround to packet reordering, until we can figure out a better solution"
This reverts commit 80ba24d512.
