Hello,

TC_TBF man page seem outdated (even in latest version of iproute2) and
doesn't explain what those two parameters do:

# tc qdisc add tbf help
Usage: ... tbf limit BYTES burst BYTES[/BYTES] rate KBPS [ mtu
BYTES[/BYTES] ]
        [ peakrate KBPS ] [ latency TIME ] [ overhead BYTES ] [ linklayer
TYPE ]

 - overhead ?
 - linklayer ?

Or did I miss something ?

Thanks,
Julien
