.SH "DESCRIPTION"
.PP
.PP
It computes cl's mode at time cl->t_c+diff and returns it. If mode
is not HTB_CAN_SEND then cl->pq_key is updated to time difference
from now to time when cl will change its state. 
Also it is worth to note that class mode doesn't change simply
at cl->{c,}tokens == 0 but there can rather be hysteresis of 
0 .. -cl->{c,}buffer range. It is meant to limit number of
mode transitions per time unit. The speed gain is about 1/6.
