None of the other drivers report this (the 'de'driver used to, but it
was so annoying that it was disabled), and both CRC and framing errors
are _very_ common on "real world" networks.

Often the cause is not fixable, or the net error rate is sufficiently 
low that they can be ignored.  The right thing to do is to increment 
the input error count, and leave these messages as tunable options.
