This code is unnecessary as the read index is already correct.
Furthermore, it can cause hangs in some situations where the packet
SHOULD be marked as not complete. This causes a bug where the read index
is incremented by 1 multiple times, causing the packet processor to read
an invalid packet, followed by a hang after it does nothing.
