Please also add some details on how the UDP BPF_SOCK_OPS_TS_TCP_SND_CB (or to be

I think I will rename it as you said. But I wonder if I can add more
details about UDP after this series gets merged which should not be
too late. After this series, I will carefully consider and test how we
use for UDP type.
Not asking for a full UDP implementation, having this set staying with TCP is
ok. We have pretty clear idea on all the new TS_*_CB will work in UDP except the
TS_SND_CB.
I am asking at least a description on where this SND hook will be in UDP and how
the delay will be measured from the udp_sendmsg(). I haven't looked, so the
question. It is better to get some visibility first instead of scrambling to
change it after landing to -next.
