Transport Hangout 05 Oct 2017

jegg@ has a patch for locking fixes here: https://reviews.freebsd.org/D12586

jegg@ has also been looking at socket errors and has these up for review: https://reviews.freebsd.org/D12575, https://reviews.freebsd.org/D12583

There may be an issue in tcp_lro.c where we check the timestamp, to make sure that it doesn't go backwards. tuexen@ suggests that this can be tested using packetdrill in remote mode.
