* Use sync.Pool for objects in packet path. Seeing cases of forwarding latency spikes that aling with GC. This might be a bit overkill, but using sync.Pool for small + short-lived objects in packet path. Before this, all these were increasing in alloc_space heap profile samples over time. With these, there is no increase (actually the lines corresponding to geting from pool does not even show up in heap accounting when doing `list` in `pprof`) * merge * Paul feedback
