Isn't the code self-documenting?  :)  This global lets any of the 
protocol processing routines force a restart or abort.  Not very pretty, 
that's for sure...  All of the action takes place in the call to 
eth_rx(), which calls a network driver's 'recv()' function, which 
generally calls NetReceive(), which then switches on protocol and may 
set NetState.  Good thing we're single threaded.
