Re: [PATCH net] secure_seq: downgrade to per-host timestamp offsets

Unfortunately too many devices (not under our control) use tcp_tw_recycle=1,
which depends on timestamps being identical of the same saddr.

Although tcp_tw_recycle got removed in net-next we can't make
such end hosts disappear so downgrade to per-host timestamp offsets.

Ok, applied and queued up for -stable.

David, I can cook a stable patch using jhash if needed, just let me know
(siphash was added after 4.10).

Yes, I'll need that, thanks!
