The signal and noise are forced to be positive since ethtool
deals in unsigned 64-bit values and this number should be human
readable. This gives easy access to some of the data formerly
exposed in the deprecated /proc/net/wireless file.
Uh, that's misleading, the signal and noise values are typically negative, so one needs to think about mentally adding a minus sign if he/she wants to
understand it. Does not ethtool know about 32-bits signed integers?
Ethtool stats only supports u64. I think it's easy enough for
humans or programs to add the negative sign. Can signal or noise
ever be > 0? If so, that could actually break something that depends
on flipping the value to negative....
Thanks,
Ben
