| Subject: | additional interface statistics |
I notice there's a few useful statistics which aren't
captured by IO::Interface , or perhaps I've just missed them
The 'Link Speed', 'Link Duplex', 'Autonegotiate' seem to be
missing. I have a quick few lines for ndd here to get these statistics.
You'll need to be root to use them ( of course ). While it's a bit
dirty, with some cleanup I thought you might want to gather these
statistics into IO::Interface with a requirement on root access or
setuid root for ndd.
