====== Discussion ======
  * tuexen discussed how to mitigate blackhole detection problems
    * tuexen@ has a review to ensure we don't do blackhole detection once we are at the minimum value [[https://reviews.freebsd.org/D24308|D24308]]; committed
    * Discussion on what should trigger blackhole detection -- full size? Or, even smaller messages which are above our min MTU? For at least IPv6, min MTU makes sense.
    * Otherwise, tuexen@'s plan remains unchanged.
    * BBR and RACK needs some modifcation
  * Discussion of [[https://reviews.freebsd.org/D24237|D24237]]: rscheff@ changed both the in-order and out-of-order data path so we call sorwakeup_locked() [when necessary] after the SACK blocks are updated. Still ongoing. rrs@ will review.
  * [[https://reviews.freebsd.org/D24657|D24657]]: Waiting for testing by %%NetApp%%.
  * [[https://reviews.freebsd.org/D24902|D24902]]: Use nsec granularity instead ticks to allow other use cases. Will be done in two steps to keep Netflix tree in sync with respect to the black box logging.
  * [[https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241958|PR241958]]: rrs is working on it.
  * Clarification of handling the sackOK option. rscheff will review the code.
  * [[https://reviews.freebsd.org/D25016|D25016]]: Improve after idle. Don't overload variables and introduce a new variable.
  * [[https://reviews.freebsd.org/D25065|D25065]]: Cubic for large time of being app limited. Approved.
  * [[https://reviews.freebsd.org/D25066|D25066]]: Improve dd. Approved.
  * [[https://reviews.freebsd.org/D24869|D24869]]: It was concluded that this should not hit head before the discussion at the IETF is over.

Next meeting: 4 June @ 1700 UTC (DIFFERENT TIME!)
