Attendees: Michael, Richard, and Jonathan

===== Discussion =====
  * JTL to poll attendees on time slot to see if the earlier (Northern Hemisphere summer) time slot would increase attendance.
  * Next meeting: Jonathan is a maybe; Michael will run if Jonathan misses the meeting.
  * Update on the interesting problem with packet lookup returning the wrong TCB. Fixed. (Thanks, Michael!) See: [[https://reviews.freebsd.org/D22971|D22971]].
  * Whitespace cleanup: [[https://reviews.freebsd.org/D22704|D22704]]. rrs@ and tuexen@ reviewed.
    * We had extensive debate about this. jtl@ will send an email to kib@ and glebius@ asking for their opinion.
  * Cleanup (combine sack_newdata and snd_recover and reclaim one 32-bit integer): [[https://reviews.freebsd.org/D18811|D18811]]. Michael will test.
  * Improve [[https://tools.ietf.org/html/rfc6675|RFC 6675]] support: [[https://reviews.freebsd.org/D18624|D18624]], [[https://reviews.freebsd.org/D18985|D18985]]. Reviews needed.
  * Add [[https://tools.ietf.org/html/rfc6937|RFC 6937]] support: [[https://reviews.freebsd.org/D18892|D18892]]. Richard plans to test more before proposing we commit this. Also, needs reviews.
  * No update on blackhole detection.
  * Don't delay ACKs for segments with ECN CWR flag [[https://reviews.freebsd.org/D22670|D22670]]: Michael will commit.
  * Fix IP ECN codepoint for SACK retransmissions [[https://reviews.freebsd.org/D23118|D23118]]: Michael will look at it
  * Fix RTO timer during SACK retransmissions [[https://reviews.freebsd.org/D23160|D23160]]: Idea is correct; questions about implementation. JTL and Michael will try to look.
  * Fix delayed ACK during TFO server-side open handling [[https://reviews.freebsd.org/D23212|D23212]]: Looks good.
