[OpenWrt-Devel] [PATCH v2 4/7] treewide: move MAC address patch functions to common library
Adrian Schmutzler
freifunk at adrianschmutzler.de
Sun Sep 22 05:57:14 EDT 2019
This unifies MAC address patch functions and moves them to a
common script. While those were implemented differently for
different targets, they all seem to do the same. The number of
different variants is significantly reduced by this patch.

v2: rebased, put chksum calculation into separate function
