[lug] Interface stats getting zeroed

[Lee Woodworth]

Hi All,
On a 3.17.7 kernel, the packet stats for only the
internet connected interface are intermittently
getting zeroed. This is well before a possible
32-bit counter rollover:

At 12:01PM:

RX packets 3952530  bytes 298884644 (285.0 MiB)
RX errors 0  dropped 371  overruns 0  frame 0
TX packets 173181  bytes 106932789 (101.9 MiB)
TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

At 18:01PM:

RX packets 38581  bytes 2532445 (2.4 MiB)
RX errors 0  dropped 371  overruns 0  frame 0
TX packets 843  bytes 345803 (337.6 KiB)
TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

I am not finding anything on the web that would explain
this. As far as I can tell remotely, the interface
is not being brought down and restarted.

Anyone have an idea of what might be causing this?
Like is this the result of a known attack?
