[PATCH net-next 0/5] net/sched: netem: cleanups and improvements

[Stephen Hemminger <stephen@networkplumber.org>]

This series modernizes the netem qdisc with several cleanups and
two functional improvements. It is independent of the bug fixes
that are in process on the net branch.

The first three patches are housekeeping: replacing pr_info() calls
with proper netlink extack error reporting, removing unused struct
members that only existed to declare enum constants, and dropping
a version string that was never updated.

The fourth patch adds per-impairment extended statistics
(delayed, dropped, corrupted, duplicated, reordered, ecn_marked)
reported via TCA_STATS_APP, following the pattern established by
RED and FQ_CODEL. A companion iproute2 patch for display will
follow separately.

The fifth patch improves the corruption path to handle
multi-segment skbs using skb_header_pointer()/skb_store_bits(),
replacing the previous code that only flipped bits in the linear
header region.
