I tried to split it a bit, maybe I could even go further and split by TRACE_EVENT_CLASS() changes, but not sure if it adds any value. But at least all preparation patches are separate. I wasn't sure if I should just remove tcp_hash_fail() as I did in this version, or rather put it under CONFIG_TCP_..., making it disabled by default and with a warning of deprecated, scheduled for removal. Maybe this won't cause any problems for anybody and I'm just too cautious of breaking others. Anyways, version 1, thanks for any reviews!
