NAME
       ata_id_xfermask - Compute xfermask from the given IDENTIFY data

SYNOPSIS
       unsigned long ata_id_xfermask(const u16 * id);

ARGUMENTS
       id
           IDENTIFY data to compute xfer mask from

DESCRIPTION
       Compute the xfermask for this device. This is not as trivial as it seems if we must
       consider early devices correctly.

       FIXME: pre IDE drive timing (do we care ?).

       LOCKING: None.

RETURN
       Computed xfermask
