r8152: fix tx packets accounting

2018-02-27T02:01:53+00:00

r8152 driver handles TSO packets (limited to ~16KB) quite well, but pretends each TSO logical packet is a single packet on the wire. There is also some error since headers are accounted once, but error rate is small enough that we do not care. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

r8152: set rx mode early when linking on

2018-02-03T00:19:00+00:00

Set rx mode before calling netif_wake_queue() when linking on to avoid the device missing the receiving packets. The transmission may start after calling netif_wake_queue(), and the packets of resopnse may reach before calling rtl8152_set_rx_mode() which let the device could receive packets. Then, the packets of response would be missed. Signed-off-by: Hayes Wang Signed-off-by: David S. Miller

r8152: fix wrong checksum status for received IPv4 packets

2018-02-03T00:19:00+00:00

The device could only check the checksum of TCP and UDP packets. Therefore, for the IPv4 packets excluding TCP and UDP, the check of checksum is necessary, even though the IP checksum is correct. Take ICMP for example, The IP checksum may be correct, but the ICMP checksum may be wrong. Signed-off-by: Hayes Wang Signed-off-by: David S. Miller

r8152: disable RX aggregation on Dell TB16 dock

2018-01-17T20:38:56+00:00

r8153 on Dell TB15/16 dock corrupts rx packets. This change is suggested by Realtek. They guess that the XHCI controller doesn't have enough buffer, and their guesswork is correct, once the RX aggregation gets disabled, the issue is gone. ASMedia is currently working on a real sulotion for this issue. Dell and ODM confirm the bcdDevice and iSerialNumber is unique for TB16. Note that TB15 has different bcdDevice and iSerialNumber, which are not unique values. If you still have TB15, please contact Dell to replace it with TB16.

r8152: move calling delay_autosuspend function

2017-06-16T15:37:13+00:00

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(). Signed-off-by: Hayes Wang Signed-off-by: David S. Miller

r8152: split rtl8152_resume function
