Merge branch 'man-page-fixups' into next

Stephen Hemminger  says:

====================

AI does a great job of finding and fixing manual pages.
This patch series is the result of editorial review and correction of
subsystem man pages, addressing grammatical errors, style inconsistencies, and
clarity issues throughout the documentation.

The corrections cover the following subsystems:
  - DCB (Data Center Bridging)
  - devlink
  - Statistics tools (lnstat, rtacct, nstat)
  - netshaper
  - TIPC
  - vdpa
  - RDMA

Common patterns corrected across all man pages:
  - Subject-verb agreement and singular/plural consistency
  - Missing or incorrect articles (a, an, the)
  - Inconsistent verb tenses in command descriptions
  - Missing terminal punctuation in examples and descriptions
  - Overly long section headers (split into concise headers + body text)
  - Awkward or non-idiomatic English phrasing
  - Copy-paste errors (e.g., incorrect titles from template files)
  - Formatting issues (duplicate markup, missing commas in cross-references)

All corrections are purely editorial. No functional changes have been made, and
all technical content remains accurate. The documentation now maintains consistent
style and proper grammar while preserving the original technical information.

Total corrections: approximately 100+ individual fixes across 40+ man page files.
