Create EtherDevBase which both Sinic and NSGigE derive from
bump fifos
drop rx max copy size to 1514 bytes to be friendlier with linux
default interrupt delay is 10us
dev/ns_gige.cc:
Shuffle around parameters to make it easier to find stuff
dev/sinic.cc:
Shuffle around parameters to make it easier to find stuff
rename cycleTime -> clock
dev/sinic.hh:
rename cycleTime -> clock
