Ok, I had her run the release kernel (-23) and the issue is there too:
$ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 1c:75:08:5a:9f:b1  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:4294744618 errors:4293631228 dropped:4294521940 overruns:4294744618 frame:4294967295

          Interrupt:45 

At this point, I think this bug can be closed. I'm not particularly
interested in fixing it since it is unrelated to the networking issues I
saw with -57. -58 seems to resolve the weird network issues she was
having so I think I'm good. Feel free to reopen if someone else can
reproduce and wants to pursue fixing it. Thanks!

Title:
  incorrect ifconfig output for unused wired ethernet

Status in “linux” package in Ubuntu:
  Won't Fix

Bug description:
  I was trying to diagnose network problems on this machine and found that Ubuntu 12.04 will show the following with ifconfig after a little while:
  $ ifconfig eth0
  eth0      Link encap:Ethernet  HWaddr 1c:75:08:5a:9f:b1
            UP BROADCAST MULTICAST  MTU:1500  Metric:1
            RX packets:4294869934 errors:4294383121 dropped:4294772570 overruns:4294869933 frame:4294967295
            TX packets:4294869933 errors:4294577844 dropped:0 overruns:4294869933 carrier:4294967295
            collisions:4294480481 txqueuelen:1000
            RX bytes:4294869934 (4.2 GB)  TX bytes:4294869933 (4.2 GB)
            Interrupt:45

  eth0 is the wired ethernet and is not in use on this machine. The
  machine is only using wlan0. I don't know if the network issues I am
  seeing on the machine relate to this or not. I'm not sure when this
  came up-- -55, -56, -57 and -58 all exhibit the problem (though, I
  don't have a simple reproducer-- it seems to come up after using the
  network for a while). -23 didn't produce the problem with the testing
  I performed (ie, within the same amount of time that it would show up
  with the other kernels). linux-generic-lts-saucy also didn't show it,
  but I couldn't run that kernel for very long because the nvidia-304
  driver didn't work properly there.
