udev duplicates entries in 70-persistent-net.rules
Status in systemd package in Ubuntu:
Fix Released
Status in systemd source package in Trusty:
Confirmed
Status in systemd package in Debian:

Bug description:
After a fresh installation of 14.04, I had various troubles with the ethernet NIC. Long story short, there were duplicate entries in /etc/udev/rules.d/70-persistent-net.rules .
The 70-persistent-net.rules file has 5 entries for a 4 port NIC (Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe).
