1. NAME▲

cable_is_40wire - 40/80/SATA decider

2. SYNOPSIS ▲

int cable_is_40wire(struct ata_port *  ap );

3. ARGUMENTS ▲

ap
    port to consider

4. DESCRIPTION ▲

This function encapsulates the policy for speed management in one place. At the moment we donAqt cache the result but there is a good case for setting ap->cbl to the result when we are called with unknown cables (and figuring out if it impacts hotplug at all).

Return 1 if the cable appears to be 40 wire.
