2014-03-07r8152: support IPv6hayeswang1-3/+103
Support hw IPv6 checksum for TCP and UDP packets. Note that the hw has the limitation of the range of the transport offset. Besides, the TCP Pseudo Header of the IPv6 TSO of the hw bases on the Microsoft document which excludes the packet length. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-03-07r8152: replace spin_lock_irqsave and spin_unlock_irqrestorehayeswang1-16/+12
Use spin_lock and spin_unlock in interrupt context. The ndo_start_xmit would not be called in interrupt context, so replace the relative spin_lock_irqsave and spin_unlock_irqrestore with spin_lock_bh and spin_unlock_bh.

2014-03-05r8152: disable the ECM modehayeswang1-6/+9
There are known issues for switching the drivers between ECM mode and vendor mode. The interrup transfer may become abnormal. The hardware may have the opportunity to die if you change the configuration without unloading the current driver first, because all the control transfers of the current driver would fail after the command of switching the configuration. Although to use the ecm driver and vendor driver independently is fine, it may have problems to change the driver from one to the other by switching the configuration. Additionally, now the vendor mode driver is more powerful than the ECM driver. Thus, disable the ECM mode driver, and let r8152 to set the configuration to vendor mode and reset the device automatically. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>.

2013-11-20r8152: support stopping/waking tx queuehayeswang1-0/+22
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>
2013-11-20r8152: modify the tx flowhayeswang1-43/+3
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>
2013-11-20r8152: fix tx/rx memory overflowhayeswang1-13/+17
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.
