commit 2f5dbd056b8be344b5492835b0924f6cf463ba4d Author: Sven Eckelmann sven@narfation.org Date: Thu Oct 25 18:22:45 2018 +0200
batctl: Allow to enable/disable subcommands
Systems with limited space are usually not using all the functionality of batman-adv and of batctl. Still, most of the batctl is still build even when the corresponding batman-adv functionality would not be available. This becomes especially important for subcommands which implement most functionality in userspace when it was previously completely handled by the kernel.
An external build system for such system can now just select the commands it really needs. Combining this with link-time-optimizationa and/or function/data-section garbage collection allows to find the right mix between size and functionality.
