gluon-core: assert WiFi driver provides 4 MAC-addresses (#1626)

David Bauer authored Feb 11, 2019 and Matthias Schiffer committed Feb 11, 2019

Gluon has multiple ways to obtain unique MAC-addresses. They are either
provided by the WiFi driver or derived from the primary MAC-address.

Quoting the same file:

> vary on a single hardware interface, since some chips are using
> a hardware MAC filter. (e.g 'rt305x')

This currently fails in case the rt35xx based chips mac address differs
from the primary MAC. In this case, the MAC address for the client0 radio
(vif 1) comes from the WiFi driver. As there is only a single
MAC-address provided by '/sys/class/ieee80211/phyX/addresses' but the
MAC-address for mesh 0 (vif 2) is derived from the Node-ID, resulting in
different first 45 bits. The WiFi won't come up altogether in this case.

This commit verifies at least 4 MAC-Addresses are provided by the WiFi
driver. If this is not the case, all MAC-addresses are derived from the
primary MAC. This way, affected radios are working correctly.

Issues & Feature requests

Before opening an issue, make sure to check whether any existing issues (open or closed) match. If you're suggesting a new feature, drop by on IRC or our mailinglist to discuss it first.

We maintain a Roadmap for the future development of Gluon.

Use a release!

Please refrain from using the master branch for anything else but development purposes! Use the most recent release instead. You can list all releases by running git tag and switch to one by running git checkout v2018.2 && make update.

If you're using the autoupdater, do not autoupdate nodes with anything but releases. If you upgrade using random master commits the nodes will break eventually.
