Subject: [PATCH iproute2 v2] 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/.
Inside iproute2 repository, the completion code is in a new
`bash-completion` toplevel directory.
v2: Remove `if` statement in Makefile: do not try to install in
/etc/bash_completion.d/ if /usr/share/bash-completion/completions/
is not found; instead, the user can override the installation path
with the specific environment variable.
