2014-07-08r8152: increase the tx timeouthayeswang1-1/+1
When the system is too busy to complete the urb, the tx timout function would be called. This causes the other tx urbs would be killed, too. Increase the tx timeout to avoid it. Signed-off-by: Hayes Wang <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2014-05-13net: get rid of SET_ETHTOOL_OPSWilfried Klaebe1-1/+1
net: get rid of SET_ETHTOOL_OPS Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.

2014-04-12r8152: check RTL8152_UNPLUGhayeswang1-0/+48
When the device is unplugged, the driver would try to disable the device. Add checking the flag of RTL8152_UNPLUG to skip setting the device when it is unplugged. This could shorten the time of unloading the driver. Signed-off-by: Hayes Wang <[email protected]> Signed-off-by: David S. Miller <[email protected]>

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 <[email protected]> Signed-off-by: David S. Miller <[email protected]>
