cable_is_40wire(9)
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 donīt 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.
