Subject: [PATCH] ethtool: Add bash-completion script
To aid users constructing a valid ethtool invocation, create a
[bash-completion] script to provide [programmable completion] of ethtool
arguments. It supports all current command options.
The script is placed in shell-completion/bash and installed to
completionsdir from pkg-config for bash-completion, similar to [kmod].
It requires pkg-config 0.18 or later to be installed on the build
system which runs aclocal (for the PKG_CHECK_MODULES m4 macro).
Note: In [scop/bash-completion#289] the bash-completion maintainer
suggested shipping this completion with ethtool rather than
bash-completion, due to assumptions about the ethtool command-line
format made by the script. That pull request also contains an extensive
test suite in Python which is not included in this commit, but may be
ported to a format suitable for inclusion if there is sufficient
interest and agreement about how to achieve that.
