The maximum packet number which a tx aggregation buffer could contain
is the buffer size / (packet size + descriptor size).
If the tx buffer is empty and the tx queue length is more than the
maximum value which is

This is racy.
You have nothing which synchronizes r8152_tx_agg_fill() and
rtl8152_start_xmit(),
therefore:
+ if (netif_queue_stopped(tp-netdev))
+ netif_wake_queue(tp-netdev);

A netif_stop_queue() can occur right

If the situation occurs, it means there is no tx buffer at
that time. If the
netif_wake_queue() is called, only one more packet would be
queued and the tx
queue would be stopped again after calling
rtl8152_start_xmit(). That is, it
is
The maximum packet number which a tx aggregation buffer could contain
is the buffer size / (packet size + descriptor size).
If the tx buffer is empty and the tx queue length is more than the
maximum value which is defined above, stop the tx queue. Wake the tx
queue after any queued packet is
