net: Allow filtering on debug traces in the net subsystem
Add several levels of DEBUG prints so that you can limit the noise to the severety of your problem. DEBUG_LL_STATE = Link local state machine changes DEBUG_DEV_PKT = Packets or info directed to the device DEBUG_NET_PKT = Packets on info on the network at large DEBUG_INT_STATE = Internal network state changes Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
