Channel 0 becomes bottom
priority
Channel 1 becomes bottom
priority.
The priority of channel 0, which
was higher than channel 1, is also
shifted.
Channel 2 becomes bottom
priority.
The priority of channels 0 and 1,
which were higher than channel 2,
are also shifted. If immediately
after there is a request to transfer
channel 5 only, channel 5 becomes
bottom priority and the priority of
channels 3 and 4, which were
higher than channel 5, are also
shifted.
Priority order does not change.
