Quick update, commenting out "dns=dnsmasq" in
/etc/NetworkManager/NetworkManager.conf has kept me up for a couple of
hours now without the issue.

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.
