  [questing][linux-6.17][iproute2] regression causing system test
  failures

Bug description:
  At this point in time, with the 6.17.0-5.5 kernel and iproute2
  6.16.0-1ubuntu2, the following OVN system tests fail on Questing:

      DNAT and SNAT on distributed router - N/S - IPv6
      Traffic to router port via LLA
      egress qos
      LR with SNAT fragmentation needed for external server

  Downgrading iproute2 to 6.14.0-1ubuntu1 makes the following tests
  pass:

      egress qos

  Mainline test with v6.16 and iproute2 6.14.0-1ubuntu1 makes all above
  mentioned tests work.

  Kernel/iproute2 from previous Ubuntu versions also make all above
  mentioned tests work.
