Subject: Install udev rules and scripts needed for compat_firmware_class
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=96c8b2c208fee5a33e9c7b7a1d8e129d1aefe21b;p=openwrt%2Fstaging%2Fblogic.git

Install udev rules and scripts needed for compat_firmware_class

If you are a distribution maintainer and your distribution has
lsb_release and if you disagree with the way we handle the
uknown case just go ahead and add a case for yourself in
scripts/compat_firmware_install along with a directory and
your own files.
