Description Dave Reisner 2014-06-04 14:33:31 UTC 
Commit 505f8da73 is responsible for downstream bug:

https://bugs.archlinux.org/task/40675

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.
Comment 1 Dave Reisner 2014-06-04 16:48:52 UTC 
Root cause is that nothing ever assigns the MAC address in link_new() or link_initialized() now that udev has been pushed out of the code path.
