git: 5d8fd932e418 - main - This brings into sync FreeBSD with the netflix versions of rack and bbr. This fixes several breakages (panics) since the tcp_lro code was committed that have been reported. Quite a few new features are now in rack (prefecting of DGP -- Dynamic Goodput Pacing among the largest). There is also support for ack-war prevention. Documents comming soon on rack..

Out of curiosity, did anyone take the time to audit/review the changes
