      usbnet: mcs7830: rework link state detection · 8d88bbff
      由 Octavian Purdila 提交于 
      Even with the quirks in commit dabdaf0c (mcs7830: Fix link state
detection) there are still spurious link-down events for some chips
where the false link-down events count go over a few hundreds.

This patch takes a more conservative approach and only looks at
link-down events where the link-down state is not combined with other
states (e.g. half/full speed, pending frames in SRAM or TX status
information valid). In all other cases we assume the link is up.

Tested on MCS7830CV-DA (USB ID 9710:7830).

      r8152: support stopping/waking tx queue · dd1b119c
      由 hayeswang 提交于 
      The maximum packet number which a tx aggregation buffer could contain
is the tx_qlen.

	tx_qlen = buffer size / (packet size + descriptor size).

If the tx buffer is empty and the queued packets are more than the
maximum value which is defined above, stop the tx queue. Wake the
tx queue if tx queue is stopped and the queued packets are less than
tx_qlen.

      r8152: modify the tx flow · 61598788
      由 hayeswang 提交于 
      Remove the code for sending the packet in the rtl8152_start_xmit().
Let rtl8152_start_xmit() to queue the packet only, and schedule a
tasklet to send the queued packets. This simplify the code and make
sure all the packet would be sent by the original order.

      r8152: fix tx/rx memory overflow · 7937f9e5
      由 hayeswang 提交于 
      The tx/rx would access the memory which is out of the desired range.
Modify the method of checking the end of the memory to avoid it.

For r8152_tx_agg_fill(), the variable remain may become negative.
However, the declaration is unsigned, so the while loop wouldn't
break when reaching the end of the desied memory. Although to change
the declaration from unsigned to signed is enough to fix it, I also
modify the checking method for safe. Replace

		remain = rx_buf_sz - sizeof(*tx_desc) -
			 (u32)((void *)tx_data - agg->head);

with

		remain = rx_buf_sz - (int)(tx_agg_align(tx_data) - agg->head);

to make sure the variable remain is always positive. Then, the
overflow wouldn't happen.

For rx_bottom(), the rx_desc should not be used to calculate the
packet length before making sure the rx_desc is in the desired range.
Change the checking to two parts. First, check the descriptor is in
the memory. The other, using the descriptor to find out the packet
length and check if the packet is in the memory.
