John Daley 04e8ec7419 net/enic: consolidate and remove some defines 
There were defines which originally allowed sharing of some code with
the enic kernel driver. The code has long since diverged and now the
abstraction just makes the code harder to read. Mostly mechanical
replacement of defines and reformatting.
