I tend to take the view that crashing is worse than not crashing, so we should ensure something appears in releng/11.0 that is suitable to ship in a release — at the very least this patch. However, we do need to be careful about packet reordering, as it can be extremely hard to diagnose while leading to observable performance degradation, which is clearly not the goal of enabling higher netisr thread counts. The change required to do this properly should be extremely small, and it’s worth getting it sorted out and merged for the release, if we can.
