1239 * is probably unjustified.  Note that these buffers do not need to be
1240 * adjacent - we just group them to simplify allocation of the bus-visible
1241 * buffer.
1242 *
1243 * XXX Note that for some reason, if MLY_MMBOX_COMMANDS is > 64, the controller
1244 * fails to respond to the command at (MLY_MMBOX_COMMANDS - 64).  It's not
1245 * wrapping to 0 at this point (determined by experimentation).  This is not
1246 * consistent with the Linux driver's implementation.
1247 * Whilst it's handy to have lots of room for status returns in case we end up
1248 * being slow getting back to completed commands, it seems unlikely that we
1249 * would get 64 commands ahead of the controller on the submissions side, so
1250 * the current workaround is to simply limit the command ring to 64 entries.
