The MTU throttle-down if a RNDIS device doesn't support a particular
packet size is being incorrectly logged. The attempted packet size is
being clobbered before it gets logged.
First patch; please inform if I'm doing this incorrectly. Diff'd
against latest official source as per the FAQ; forward port to current
git version is straightforward.
