[PATCH] /proc/net/dev counter fix, linux-2.5.0

[Miika Pekkarinen]

I have made a patch to fix the counter values in /proc/net/dev. The
problem was that the tx_bytes and rx_bytes will reset when ~4GB is
transferred. This patch has been tested to work with linux-2.5.0 but it
should work on all 2.4.* kernels. Also it should work with most of the
interface cards but not all yet.

This is the first version of my patch so please give me some comments
about it.
