Title:
Wired disconnects due to add_object(): Netlink error adding 0.0.0.0/0
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
I have a Lenovo Thinkpad E540 with r8169 wired onboard networking.
After 15-30 minutes use the network stops working. There are no
messages in dmesg, link stays up etc.
This is output to journal:

Disconnecting and reconnecting the cable solves the issue until next
reboot, so I don't think it's a DHCP configuration issue. Other PC's
on the network work fine.
This has also been reported as kernel bug #1459985 as it's still
unknown what causes the issue.
