(TDT is allowed to be numerically smaller than the initial TDH - value; wrapping at or above TDLEN bytes to zero is normal.) The failsafe - that QEMU currently has here is a check against reaching the original - TDH value again -- a complete wraparound, which should never happen. - -- In the receive case RDH is increased from its initial value until - "total_size" bytes have been received; preferably in a single step, or - in "s->rxbuf_size" byte steps, if the latter is smaller.
