r8152: disable DelayPhyPwrChg

2020-02-05T21:22:50+00:00

[ Upstream commit aa475d935272481c9ffb1ae54eeca5c1819fbe1a ]

When enabling this, the device would wait an internal signal which
wouldn't be triggered. Then, the device couldn't enter P3 mode, so
the power consumption is increased.

r8152: avoid the MCU to clear the lanwake

2020-02-05T21:22:50+00:00

[ Upstream commit 19813162895a696c5814d76e5f8fb6203d70f6e0 ]

Avoid the MCU to clear the lanwake after suspending. It may cause the
WOL fail. Disable LANWAKE_CLR_EN before suspending. Besides,enable it
and reset the lanwake status when resuming or initializing.

r8152: disable test IO for RTL8153B

2020-02-05T21:22:50+00:00

[ Upstream commit d7f1b59655efb5a285d227c8f9853a98eab5c2fd ]

For RTL8153B with QFN32, disable test IO. Otherwise, it may cause
abnormal behavior for the device randomly.

r8152: Disable PLA MCU clock speed down

2020-02-05T21:22:50+00:00

[ Upstream commit 08997b5eec08a2c29367f19a74abdea54b299406 ]

PLA MCU clock speed down could only be enabled when tx/rx are disabled.
Otherwise, the packet loss may occur.

r8152: get default setting of WOL before initializing

[ Upstream commit 9583a3638dc07cc1878f41265e85ed497f72efcb ]

Initailization would reset runtime suspend by tp->saved_wolopts, so
the tp->saved_wolopts should be set before initializing.

[ Upstream commit a9ff44f0e61d074f29770413fef6a5452be7b83e ]

RM500Q is a 5G module from Quectel, supporting both standalone and
non-standalone modes. The normal Quectel quirks apply (DTR and dynamic
interface numbers).

net: usb: lan78xx: Add .ndo_features_check

2020-01-29T15:45:21+00:00

[ Upstream commit ce896476c65d72b4b99fa09c2f33436b4198f034 ]

As reported by Eric Dumazet, there are still some outstanding
cases where the driver does not handle TSO correctly when skb's
are over a certain size. Most cases have been fixed, this patch
should ensure that forwarded SKB's that are greater than
MAX_SINGLE_PACKET_SIZE - TX_OVERHEAD are software segmented
and handled correctly.

r8152: add missing endpoint sanity check

2020-01-23T07:22:51+00:00

[ Upstream commit 86f3f4cd53707ceeec079b83205c8d3c756eca93 ]

Add missing endpoint sanity check to probe in order to prevent a
NULL-pointer dereference (or slab out-of-bounds access) when retrieving
the interrupt-endpoint bInterval on ndo_open() in case a device lacks
the expected endpoints.

net: usb: lan78xx: limit size of local TSO packets

2020-01-23T07:22:50+00:00

[ Upstream commit f8d7408a4d7f60f8b2df0f81decdc882dd9c20dc ]

lan78xx_tx_bh() makes sure to not exceed MAX_SINGLE_PACKET_SIZE
bytes in the aggregated packets it builds, but does
nothing to prevent large GSO packets being submitted.

Pierre-Francois reported various hangs when/if TSO is enabled.

For localy generated packets, we can use netif_set_gso_max_size()
to limit the size of TSO packets.

Note that forwarded packets could still hit the issue,
so a complete fix might require implementing .ndo_features_check
for this driver, forcing a software segmentation if the size
of the TSO packet exceeds MAX_SINGLE_PACKET_SIZE.
