Author: adrian

New Revision: 319582
URL: https://svnweb.freebsd.org/changeset/base/319582

Log:
  [iwm] Ignore IWM_DEBUG_LOG_MSG notifications.
  
  * Firmware versions 21 and 22 generate some IWM_DEBUG_LOG_MSG notifications,
    which seem to be harmless. Avoid spamming the system log with
    "frame ... UNHANDLED (this should not happen)" messages.
