        <pre>Commit 505f8da73 is responsible for downstream bug:

<a href="https://bugs.archlinux.org/task/40675">https://bugs.archlinux.org/task/40675</a>

Since this commit, mac addresses are compared to an empty dev_mac in
net_match_config, causing any MACAddress based matching rule to be ignored.

To reproduce the failure, use a .network file such as this:

[Match]
MACAddress=fe:ed:fa:ce:be:ef

[Network]
Address=10.0.3.1/24

Assuming a real MAC, the address will never be applied. Matching by other
methods, such as interface name, still work as expected.</pre>
