Merge branch 'netem-bug-fixes'
Stephen Hemminger says:
====================
netem: bug fixes
These bugs were found when doing AI-assisted review of sch_netem.c
during investigation of the packet duplication recursion problem
addressed in Jamal's series.
The fixes cover:
- probability gaps in the 4-state Markov loss model
- queue limit not accounting for reordered packets
- PRNG reseeded on every tc change, breaking reproducibility
- slot configuration not validated (inverted ranges, negative
delays, negative limits)
- slot delay arithmetic overflow for ranges above ~2.1 seconds
- negative latency and jitter wrapping to huge time_to_send
values via u64 arithmetic
