Here are the expectations for new network drivers:
1. Driver will be in driver/net.  You're not the first with hardware 
dependencies, and there are standard ways of dealing with them.
2. You must use the CONFIG_NET_MULTI-style API, where the driver is 
registered and access functions such as send, halt, recv etc. are called 
through a struct.
3. Driver is initialized through cpu_eth_init() or board_eth_init()

Without meeting these, your code will not be accepted.
