// Retry counts -
//
// When moving a byte to/from the FIFO, we sit in a tight loop for a while
// waiting for the controller to become ready.  The number of times through
// the loop is controlled by FIFO_TIGHTLOOP_RETRY_COUNT.  When that count
// expires, we'll wait in 10ms increments.  FIFO_DELAY_RETRY_COUNT controls
// how many times we wait.
//
// The ISR_SENSE_RETRY_COUNT is the maximum number of 1 microsecond
// stalls that the ISR will do waiting for the controller to accept
// a SENSE INTERRUPT command.  We do this because there is a hardware
// quirk in at least the NCR 8 processor machine where it can take
// up to 50 microseconds to accept the command.
//
// When attempting I/O, we may run into many different errors.  The
// hardware retries things 8 times invisibly.  If the hardware reports
// any type of error, we will recalibrate and retry the operation
// up to RECALIBRATE_RETRY_COUNT times.  When this expires, we check to
// see if there's an overrun - if so, the DMA is probably being hogged
// by a higher priority device, so we repeat the earlier loop up to
// OVERRUN_RETRY_COUNT times.
//
// Any packet that is about to be returned with an error caused by an
// unexpected hardware error or state will be restarted from the very
// beginning after resetting the hardware HARDWARE_RESET_RETRY_COUNT
// times.
