Input/output octets accounting

[wlanmac]

Hmm.. good question. The answer, of course, is right there in the source
code. It depends on if you are using a tun or a tap device, where 99% of
the time, you are using a tun. The entire packet (as seen by chilli) is
counted... so, with tun, that would be the IP layer. If using a tap
interface, it is the entire Ethernet segment. 

The RADIUS RFC doesn't specify what layer to consider when counting
octets.. maybe it does make sense to only count the IP payload.. hm.
