2014-07-24r8152: fix the checking of the usb speedhayeswang
When the usb speed of the RTL8152 is not high speed, the USB_DEV_STAT[2:1] should be equal to [0 1]. That is, the STAT_SPEED_FULL should be equal to 2. There is a easy way to check the usb speed by the speed field of the struct usb_device. Use it to replace the original metheod.

2014-07-11r8152: fix r8152_csum_workaround functionhayeswang

2014-05-13net: get rid of SET_ETHTOOL_OPSWilfried Klaebe
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_UNPLUGhayeswang
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.

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. Miller <davem@davemloft.net>
