2014-03-07r8152: replace spin_lock_irqsave and spin_unlock_irqrestorehayeswang
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.

2014-03-06r8152: remove rtl8152_get_statshayeswang
The rtl8152_get_stats() returns the point address of the struct net_device_stats. This could be got from struct net_device directly. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-03-05r8152: disable the ECM modehayeswang
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.

2014-02-18r8152: combine PHY reset with set_speedhayeswang

2013-11-20r8152: support stopping/waking tx queuehayeswang
The maximum packet number which a tx aggregation buffer could contain is the tx_qlen. tx_qlen = buffer size / (packet size + descriptor size).

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: fix tx/rx memory overflowhayeswang
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.
