* r8152: fix the submission of the interrupt transferhayeswang2014-02-07
| | | | | | | | | | | The submission of the interrupt transfer should be done after setting the bit of WORK_ENABLE, otherwise the callback function would have the opportunity to be returned directly. Clear the bit of WORK_ENABLE before killing the interrupt transfer. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* drivers/net: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-01-16
| | | | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. This covers everything under drivers/net except for wireless, which has been submitted separately. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S.

* r8152: support stopping/waking tx queuehayeswang2013-11-20
| | | | | | | | | | | | | | | 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. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* r8152: modify the tx flowhayeswang2013-11-20
| | | | | | | | | | 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. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* r8152: fix tx/rx memory overflowhayeswang2013-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
