2014-09-28r8152: add functions to set EEEhayeswang
Add functions to enable EEE and set EEE advertisement. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-28r8152: change the EEE definitionhayeswang
Replace the EEE definitions with the ones which is declared in "mdio.h". Chage some definitions to make them readable. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-26r8152: fix the carrier off when autoresuminghayeswang
netif_carrier_off would be called when autoresuming, even though the cable is plugged. This causes some applications do relative actions when detecting the carrier off. Keep the status of the carrier, and let it be modified when the linking change occurs. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-09-22r8152: disable ALDPShayeswang
If the hw is in ALDPS mode, the hw may have no response for accessing the most registers. Therefore, the ALDPS should be disabled before accessing the hw in rtl_ops.init(), rtl_ops.disable(), rtl_ops.up(), and rtl_ops.down(). Regardless of rtl_ops.enable(), because the hw wouldn't enter ALDPS mode when linking on. The hw would enter the ALDPS mode after several seconds when link down occurs and the ALDPS is enabled.

2014-09-01r8152: reduce the number of Txhayeswang
Because the Tx has the features of stopping queue and aggregation, We don't need many tx buffers. Change the tx number from 10 to 4 to reduce the usage of the memory.

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.

2014-03-05r8152: 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.
