407f5f009c In div_output() explicitly set m->m_nextpkt to NULL. If divert socket 
is not userland, but ng_ksocket, then m->m_nextpkt may be non-NULL. In
this case we would panic in sbappend.

23a1a3e3a9 When used as divert socket we need to decouple stack when node is entered 
from socket side. Use ng_queue_fn() instead of ng_send_fn().

cbfa8be50b Since there is no way to queue a function call to node, create 
ng_queue_fn() - a queue version of ng_send_fn().

0ee2317201 When looking for the next hole to retransmit from the scoreboard, 
or to compute the total retransmitted bytes in this sack recovery
episode, the scoreboard is traversed. While in sack recovery, this
traversal occurs on every call to tcp_output(), every dupack and
every partial ack. The scoreboard could potentially get quite large,
making this traversal expensive.

This change optimizes this by storing hints (for the next hole to
retransmit and the total retransmitted bytes in this sack recovery
episode) reducing the complexity to find these values from O(n) to
constant time.

The debug code that sanity checks the hints against the computed
value will be removed eventually.

8455545285 A new version of NetFlow node. 
The most significant changes are:
- Use UMA zone instead of own chunk of memory.
- Lock each hash entry separately.
- Expire items "actively" - interrupt method can expire flows
  from hash slot, when it searches through it.
- Remove global tailqueue. Make callout thread search through
  every hash slot.
- Export datagram is detached from private data and filled. If
  it is incomplete, it is attached back. Another thread will
  continue working with it.

Lesser, but also important speedups:
- Flows in hash slot are stored in tailqueue. Whenever a flow is
  hit, it is moved to the begging, so it can be located quicker.
- When callout thread works with hash slot it bails out if
  slot mutex is contested.
