CONFIG_ATM_HORIZON_DEBUG: Enable debugging messages

General informations

The Linux kernel configuration item CONFIG_ATM_HORIZON_DEBUG:

Help text

Somewhat useful debugging messages are available. The choice of messages is controlled by a bitmap. This may be specified as a module argument (kernel command line argument as well?), changed dynamically using an ioctl (not yet) or changed by sending the string "Dxxxx" to VCI 1023 (where x is a hex digit). See the file drivers/atm/horizon.h for the meanings of the bits in the mask.

When active, these messages can have a significant impact on the speed of the driver, and the size of your syslog files! When inactive, they will have only a modest impact on performance.
