// Description:
// Defines the accept watchdog timer for baseband SAPs
// to guard against:
// 1) race condition in accepting a link just as the Controller drops the link
// automatically due to it Accept Timer firing
// 2) Broken HW not delivering this important event
// 3) HW that reports only via a useless Command Status event
//
