As David Laight noticed, it currently takes quite some time to find
the optimal pmtu in the Search state, and also lacks the black hole
detection in the Search Complete state. This patchset is to address
them to mke the PLPMTUD probe more effective and efficient.

v1->v2:
  - see Patch 1/2.

Xin Long (2):
  sctp: do black hole detection in search complete state
  sctp: send the next probe immediately once the last one is acked

I applied v1 of this so I'll need relative fixups.

Thank you.
