Description of problem:
The transmit and receive bytes counters displayed by ifconfig when given no
arguments reset to zero somewhere above 4077 MB, possibly at the 32-bit
unsigned integer limit of 4,294,967,295. The packet counters do not reset, as
they should not.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create lots of network traffic, the iperf program makes this easy.
2. Run ifconfig repeatedly during the test
3. Wait for just over 4 gigs worth of data to be transmitted and you'll see
the TX and/or RX byte counter reset to zero.
Actual Results: TX and RX bytes reset to zero ever 4 GB or so of data
Expected Results: TX and RX bytes should continuously climb as TX and RX
