Description of problem:
Have a linux based router installed that handles alot of traffic, handles ip
only, no other layer 3 protocols.  Connected to ethernet based network.

After a few days of operation the number of RX and TX bytes, "rolls over" to zero.  

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.  Bring up interface, let it transmit/recieve packets
2.  Bytes RX and TX "rolls over" somewhere around 3.5GB


Actual Results:  Below is an example.  Here we find 609MB recieved on this
interface in 24 million packets.  That means each packet would have an average
size of 26 bytes.  This is WELL below the minimum size for a ip packet of 64
bytes, and below the 42 bytes for arp requests.

ifconfig eth0

eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:x.x.x.x  Bcast:x.x.x.x  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:24326219 errors:1 dropped:0 overruns:0 frame:0
          TX packets:23344641 errors:6 dropped:0 overruns:3 carrier:3
          collisions:0 txqueuelen:100
          RX bytes:639544916 (609.9 Mb)  TX bytes:3244279103 (3093.9 Mb)
          Interrupt:5 Base address:0xf000

Expected Results:  ifconfig should return the proper amount of bytes recieved or
transmitted on a certain interface.

Additional info:

Despite being up(and untouched) for a number of days and routing several gigs of
information, numbers gathered via mrtg, ifconfig has never shown more then
~3gigs of recieved/transmitted on any interface.
