cable_is_40wire: 40/80/SATA decider
NAME
cable_is_40wire - 40/80/SATA decider
SYNOPSIS
-
int cable_is_40wire(struct ata_port
* ap);
ARGUMENTS
ap
-
- port to consider
DESCRIPTION
This function encapsulates the policy for speed management in one place. At the moment we don't 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.
