====== Hangout Notes 12 Jan 2017 ======

  * hiren@ is trying out RACK + BBR at LLNW.  BBR is stablish, has not crashed in the last 24 hours in a lab.

  * tuexen@ has updated packetdrill and the test suite.  gnn@ has integrated and run those on his own with no negative effects.

  * gnn@ has versions of copyoutmbuf() copyoutmubfat() that get all the data from an mbuf chain

  * tuexen@ brings up an issue when bind() and connect() are used with IPv4 mapped addresses.  The subsequent connect() sends an incorrect packet.  Illumos returns an error in this case.  %%MacOS%% also returns an error in this case.  He has a patch but wants to know what the error ought to be.  Address family not available seems to be the right answer (rstons@).

  * This bug https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=212283 deals with the change in byte order done earlier.  tuexen@ has a patch that addresses this issue, at least in part.

  * Fortville cards have issues with TSO where they cannot handle more than 8 buffers showing up in a single TSO request.  The iovec is actually 64.  rstone@ has a patch for this but wants to test this to make sure it doesn't effect other cards.

  * A thread on flowtable vs. route caching has reared its ugly head.  gnn@ commits to removing flowtable from the tree.

  * gnn@ points out that we need more slots on the call (10 is the current limit) and will look into a solution to that problem
