Is there any documentation for this global variable? I'm trying to fix a bug in NetStartAgain(), and I'm trying to understand the purpose of this variable.

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.
