2017-06-16r8152: move calling delay_autosuspend functionhayeswang
Move calling delay_autosuspend() in rtl8152_runtime_suspend(). Calling delay_autosuspend() as late as possible. The original flows are 1. check if the driver/device is busy now. 2. set wake events. 3. enter runtime suspend. If the wake event occurs between (1) and (2), the device may miss it. Besides, to avoid the runtime resume occurs after runtime suspend immediately, move the checking to the end of rtl8152_runtime_suspend().

2017-06-15r8152: add byte_enable for ocp_read_word functionhayeswang
Add byte_enable for ocp_read_word() to replace reading 4 bytes data with reading the desired 2 bytes data. This is used to avoid the issue which is described in commit b4d99def0938 ("r8152: remove sram_read"). The original method always reads 4 bytes data, and it may have problem when reading the PHY registers. The new method is supported since RTL8153B, but it doesn't influence the previous chips. The bits of the byte_enable for the previous chips are the reserved bits, and the hw would ignore them. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

2017-03-24r8152: prevent the driver from transmitting packets with carrier offhayeswang
The linking status may be changed when autosuspend. And, after autoresume, the driver may try to transmit packets when the device is carrier off, because the interrupt transfer doesn't update the linking status, yet. And, if the device is in ALDPS mode, the device would stop working. The another similar case is 1. unplug the cable. 2. interrupt transfer queue a work_queue for linking change. 3. device enters the ALDPS mode. 4. a tx occurs before the work_queue is called.

2017-01-10r8152: fix rx issue for runtime suspendhayeswang
Pause the rx and make sure the rx fifo is empty when the autosuspend occurs. If the rx data comes when the driver is canceling the rx urb, the host controller would stop getting the data from the device and continue it after next rx urb is submitted. That is, one continuing data is split into two different urb buffers. That let the driver take the data as a rx descriptor, and unexpected behavior happens.

2016-10-30r8152: Fix broken RX checksums.Mark Lord
The r8152 driver has been broken since (approx) 3.16.xx when support was added for hardware RX checksums on newer chip versions. Symptoms include random segfaults and silent data corruption over NFS. The hardware checksum logig does not work on the VER_02 dongles I have here when used with a slow embedded system CPU. Google reveals others reporting similar issues on Raspberry Pi. So, disable hardware RX checksum support for VER_02, and fix an obvious coding error for IPV6 checksums in the same function. Because this bug results in silent data corruption, it is a good candidate for back-porting to -stable >= 3.16.xx. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: David S.
