There is a ethtool mechanism to set message level for debug method, read other network drivers and look at netif_msg_timer(x), netif_msg_probe(x), etc in include/linux/netdevice.h The goal here is to not have any special configuration for each different type of hardware. It is bad user design to have each hardware vendor choosing different mechanism and values to enable debugging. You can argue that the existing infrastructure is inadequate, in which case extend the infrastructure for all devices.
