[IPROUTE2 PATCH] Fixes for tc help commands

[Hasso Tepper <hasso@estpak.ee>]

[-- Attachment #1: Type: text/plain, Size: 377 bytes --]

* "tc [class|qdisc|filter] get" doesn't exist, remove it from inline help.

* Add "replace" to "tc [class|filter] get" inline help.

* Fix "tc [class|qdisc|filter] help" output:

  ~$ tc class help
  [snip]
  Command "help" is unknown, try "tc class help".
  ~$



with my best wishes,
