4 NETIF Msg Level
7 The design of the network interface message level setting.
10 -------
18  integer variable that controls the debug message level.  The message
19  level ranged from 0 to 7, and monotonically increased in verbosity.
21  The message level was not precisely defined past level 3, but were
22  always implemented within +-1 of the specified level.  Drivers tended
23  to shed the more verbose level messages as they matured.
25    - 0  Minimal messages, only essential information on fatal errors.
26    - 1  Standard messages, initialization status.  No run-time messages
27    - 2  Special media selection messages, generally timer-driver.
28    - 3  Interface starts and stops, including normal status messages
29    - 4  Tx and Rx frame error messages, and abnormal driver operation
30    - 5  Tx packet queue information, interrupt events.
31    - 6  Status on each completed Tx packet and received Rx packets
32    - 7  Initial contents of Tx and Rx packets
34  Initially this message level variable was uniquely named in each driver
44    - Using an ioctl() call to modify the level.
45    - Per-interface rather than per-driver message level setting.
46    - More selective control over the type of messages emitted.
53   - Retaining the per-driver integer variable "debug" as a module
54     parameter with a default level of '1'.
56   - Adding a per-interface private variable named "msg_enable".  The
57     variable is a bit map rather than a level, and is initialized as::
63 	debug < 0 ? 0 : 1 << min(sizeof(int)-1, debug)
72       if (np->msg_enable & NETIF_MSG_LINK)
