Debug levels are standardized, please follow the standard.

All messages are bitmapped.  See NETIF_MSG_* and netif_msg_* in 
include/linux/netdevice.h.
Given the standard 'debug' module parameter, which takes a value from 
0-N (where N==10 or so), the driver uses netif_msg_init() to construct 
the bitmap of messages to be enabled.
