Is the volatile really needed?
The problem is that the 'packet' parameter to struct eth_device.send() is volatile, and it propagates into this function. So if I remove the volatile, I have to either add ugly casts elsewhere or change the eth_device API...
I have no idea why the network subsystem feels the need to enforce the use of volatile in all drivers, though...
