Correcting github issue #2 whereby cygwin reports 'unknown environment' when we know damn wll that the environment is cygwin. Folks need to help use support cygwin.
Moved ETH_P_* constant definitions from ether/channel.h to ether/ether.h where they belong.
Prefixed classfier related constants with 'CLASSIFIER_' to avoid confusion with some new constants that may have similar names.
