[PATCH] ipw2200: Set a meaningful silence threshold value
Set a meaningful silence threshold value (replacing our previous "0" default), which gets rid of the gratuitous "Link deterioration" notifications that we've been receiving from firmware. This notification feature tells the driver information to help it determine when to pre-emptively restart the firmware/ucode in anticipation of firmware errors! But since setting this new threshold, I haven't seen any such notifications. At least it keeps the logs a little less busy.
