Title:
  ethtool -t eth0 offline loses routing table

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  ethtool -t eth0 offline does the tests, but leaves the routing table
  with only the entry for the local network.  I had to sudo route add
  default gw 10.0.0.1, in my case.  The online test didn't do this.

  Ubuntu 14.04, ethtool 1:3.13-1

  (the martian packets are from TCP connections that my router is still
  NATing to this machine, even though without its routing table, it's
  not happy to see them.)

   And yes, my e1000e is autonegotiating to 10baseT/Full on the same
  cables and switch that still works at 1000baseT with another machine,
  hence running self-tests...  I thought this machine used to run at
  1000baseT, weird if I went 5 years without noticing my desktop being
  slow.  Not what this bug report is about, though.

   The e1000e hardware is on a DG965WH Intel mobo (ICH8 / g965 graphics, first-gen core2)

  Appears to be the same problem as someone reported to Redhat a while ago, which got marked as fixed for the igb driver
  https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=661976
  Not very useful info in their BTS, because the bug that it's a dup of is now flagged private, so nobody can even look at it.

   Possibly this is a per-driver thing, unless the right fix is to have
  ethtool save/restore the routing table entries for that iface.
