SVN rev 184414 on 2008-10-28 14:14:57Z by oleg
Type of q_time (start of queue idle time) has changed: uint32_t -> uint64_t.
This should fix q_time overflow, which happens after 2^32/(86400*hz) days of
uptime (~50days for hz = 1000).
q_time overflow cause following:
- traffic shaping may not work in 'fast' mode (not enabled by default).
- incorrect average queue length calculation in RED/GRED algorithm.
NB: due to ABI change this change is not applicable to stable.
