Subject: [PATCH net-next 0/6] net/sched: netem: cleanups and improvements
Date: Sat, 28 Mar 2026 11:26:01 -0700	[thread overview]
Message-ID: <20260328182704.456993-1-stephen@networkplumber.org> (raw)

Cleanup and improvement patches for netem, done as follow-on
to the bug fix series found during AI-assisted review.

- replace pr_info() with netlink extack error reporting
- validate slot min/max delay range on configuration
- fix slot delay calculation overflow for large ranges
- remove unused loss model struct fields
- remove stale VERSION string
- add per-impairment extended statistics (delayed, dropped,
  corrupted, duplicated, reordered, ecn_marked)

The xstats patch requires a corresponding iproute2 change
to display the new counters in tc -s qdisc show. This will go
as separate patch after this.
