Subject: [PATCH iproute2] tc: add bash-completion function
Add function for command completion for tc in bash, and update Makefile
to install it:
- Under /usr/share/bash-completion/completions/ (default).
- Or under /etc/bash_completions.d/, which is the old directory for
bash-completion, if /usr/share/bash-completion/completions/ is not
found AND /etc/bash_completions.d/ exists already.
Inside iproute2 repository, the completion code is in a new
`bash-completion` toplevel directory.
