* Many Atheros programs expect the user to enter a password to
* access a device; the password is encoded to produce the 16-bit
* Device Access Key (DAK) stored in the PIB;
*
* Vendors must publish the device password so that end users can
* reproduce the same 16-byte hexadecimal value later; a password
