UPDATING sys/netinet ip_dummynet.h Log: 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. PR: kern/128401 Revision Changes Path 1.546 +3 -0 src/UPDATING 1.42 +1 -1 src/sys/netinet/ip_dummynet.h
