Review comment:
I can keep the anchor prototype as clock_t, but the remain still needs.
remain timeout parameter needs to be calculated dynamically, this time needs
to be accumulated
```
1207 remain = tcp_send_gettimeout(anchor, remain);
1208 ret = net_timedwait_uninterruptible(&conn->snd_sem, remain);
//remain
changed
1253 remain = tcp_send_gettimeout(anchor, remain);
1254 wrb = tcp_wrbuffer_timedalloc(remain);
1255 ninfo("new wrb %p\n", wrb);
1256 DEBUGASSERT(TCP_WBPKTLEN(wrb) == 0);
...
