r8152: check disconnect status after long sleep
Dell USB Type C docking WD19/WD19DC attaches additional peripherals as:
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
|__ Port 1: Dev 11, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 3: Dev 12, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 4: Dev 13, If 0, Class=Vendor Specific Class,
Driver=r8152, 5000M
where usb 2-1-3 is a hub connecting all USB Type-A/C ports on the dock.
When hotplugging such dock with additional usb devices already attached on
it, the probing process may reset usb 2.1 port, therefore r8152 ethernet
device is also reset. However, during r8152 device init there are several
for-loops that, when it's unable to retrieve hardware registers due to
being disconnected from USB, may take up to 14 seconds each in practice,
and that has to be completed before USB may re-enumerate devices on the
bus. As a result, devices attached to the dock will only be available
after nearly 1 minute after the dock was plugged in:
[ 216.388290] [250] r8152 2-1.4:1.0: usb_probe_interface
[ 216.388292] [250] r8152 2-1.4:1.0: usb_probe_interface - got id
[ 258.830410] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): PHY not ready
[ 258.830460] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): Invalid header when reading pass-thru MAC addr
[ 258.830464] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): Get ether addr fail
This happens in, for example, r8153_init:
static int generic_ocp_read(struct r8152 *tp, u16 index, u16 size,
void *data, u16 type)
{
if (test_bit(RTL8152_UNPLUG, &tp->flags))
return -ENODEV;
...
}
static u16 ocp_read_word(struct r8152 *tp, u16 type, u16 index)
{
u32 data;
...
generic_ocp_read(tp, index, sizeof(tmp), &tmp, type | byen);
data = __le32_to_cpu(tmp);
...
return (u16)data;
}
static void r8153_init(struct r8152 *tp)
{
...
if (test_bit(RTL8152_UNPLUG, &tp->flags))
return;
for (i = 0; i < 500; i++) {
if (ocp_read_word(tp, MCU_TYPE_PLA, PLA_BOOT_CTRL) &
AUTOLOAD_DONE)
break;
msleep(20);
}
...
}
Since ocp_read_word() doesn't check the return status of
generic_ocp_read(), and the only exit condition for the loop is to have
a match in the returned value, such loops will only ends after exceeding
its maximum runs when the device has been marked as disconnected, which
takes 500 * 20ms = 10 seconds in theory, 14 in practice.
To solve this long latency another test to RTL8152_UNPLUG flag should be
added after those 20ms sleep to skip unnecessary loops, so that the device
probe can complete early and proceed to parent port reset/reprobe process.
This can be reproduced on all kernel versions up to latest v5.6-rc2, but
after v5.5-rc7 the reproduce rate is dramatically lowered to 1/30 or less
while it was around 1/2.

r8152: check disconnect status after long sleep
Dell USB Type C docking WD19/WD19DC attaches additional peripherals as:
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
|__ Port 1: Dev 11, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 3: Dev 12, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 4: Dev 13, If 0, Class=Vendor Specific Class,
Driver=r8152, 5000M
where usb 2-1-3 is a hub connecting all USB Type-A/C ports on the dock.
When hotplugging such dock with additional usb devices already attached on
it, the probing process may reset usb 2.1 port, therefore r8152 ethernet
device is also reset. However, during r8152 device init there are several
for-loops that, when it's unable to retrieve hardware registers due to
being disconnected from USB, may take up to 14 seconds each in practice,
and that has to be completed before USB may re-enumerate devices on the
bus. As a result, devices attached to the dock will only be available
after nearly 1 minute after the dock was plugged in:
[ 216.388290] [250] r8152 2-1.4:1.0: usb_probe_interface
[ 216.388292] [250] r8152 2-1.4:1.0: usb_probe_interface - got id
[ 258.830410] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): PHY not ready
[ 258.830460] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): Invalid header when reading pass-thru MAC addr
[ 258.830464] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): Get ether addr fail
This happens in, for example, r8153_init:
static int generic_ocp_read(struct r8152 *tp, u16 index, u16 size,
void *data, u16 type)
{
if (test_bit(RTL8152_UNPLUG, &tp->flags))
return -ENODEV;
...
}
static u16 ocp_read_word(struct r8152 *tp, u16 type, u16 index)
{
u32 data;
...
generic_ocp_read(tp, index, sizeof(tmp), &tmp, type | byen);
data = __le32_to_cpu(tmp);
...
return (u16)data;
}
static void r8153_init(struct r8152 *tp)
{
...
if (test_bit(RTL8152_UNPLUG, &tp->flags))
return;
for (i = 0; i < 500; i++) {
if (ocp_read_word(tp, MCU_TYPE_PLA, PLA_BOOT_CTRL) &
AUTOLOAD_DONE)
break;
msleep(20);
}
...
}
Since ocp_read_word() doesn't check the return status of
generic_ocp_read(), and the only exit condition for the loop is to have
a match in the returned value, such loops will only ends after exceeding
its maximum runs when the device has been marked as disconnected, which
takes 500 * 20ms = 10 seconds in theory, 14 in practice.
To solve this long latency another test to RTL8152_UNPLUG flag should be
added after those 20ms sleep to skip unnecessary loops, so that the device
probe can complete early and proceed to parent port reset/reprobe process.
This can be reproduced on all kernel versions up to latest v5.6-rc2, but
after v5.5-rc7 the reproduce rate is dramatically lowered to 1/30 or less
while it was around 1/2.

r8152: check disconnect status after long sleep
Dell USB Type C docking WD19/WD19DC attaches additional peripherals as:
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
|__ Port 1: Dev 11, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 3: Dev 12, If 0, Class=Hub, Driver=hub/4p, 5000M
|__ Port 4: Dev 13, If 0, Class=Vendor Specific Class,
Driver=r8152, 5000M
where usb 2-1-3 is a hub connecting all USB Type-A/C ports on the dock.
When hotplugging such dock with additional usb devices already attached on
it, the probing process may reset usb 2.1 port, therefore r8152 ethernet
device is also reset. However, during r8152 device init there are several
for-loops that, when it's unable to retrieve hardware registers due to
being disconnected from USB, may take up to 14 seconds each in practice,
and that has to be completed before USB may re-enumerate devices on the
bus. As a result, devices attached to the dock will only be available
after nearly 1 minute after the dock was plugged in:
[ 216.388290] [250] r8152 2-1.4:1.0: usb_probe_interface
[ 216.388292] [250] r8152 2-1.4:1.0: usb_probe_interface - got id
[ 258.830410] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): PHY not ready
[ 258.830460] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): Invalid header when reading pass-thru MAC addr
[ 258.830464] r8152 2-1.4:1.0 (unnamed net_device) (uninitialized): Get ether addr fail
This happens in, for example, r8153_init:
static int generic_ocp_read(struct r8152 *tp, u16 index, u16 size,
void *data, u16 type)
{
if (test_bit(RTL8152_UNPLUG, &tp->flags))
return -ENODEV;
...
}
static u16 ocp_read_word(struct r8152 *tp, u16 type, u16 index)
{
u32 data;
...
generic_ocp_read(tp, index, sizeof(tmp), &tmp, type | byen);
data = __le32_to_cpu(tmp);
...
return (u16)data;
}
static void r8153_init(struct r8152 *tp)
{
...
if (test_bit(RTL8152_UNPLUG, &tp->flags))
return;
for (i = 0; i < 500; i++) {
if (ocp_read_word(tp, MCU_TYPE_PLA, PLA_BOOT_CTRL) &
AUTOLOAD_DONE)
break;
msleep(20);
}
...
}
Since ocp_read_word() doesn't check the return status of
generic_ocp_read(), and the only exit condition for the loop is to have
a match in the returned value, such loops will only ends after exceeding
its maximum runs when the device has been marked as disconnected, which
takes 500 * 20ms = 10 seconds in theory, 14 in practice.
To solve this long latency another test to RTL8152_UNPLUG flag should be
added after those 20ms sleep to skip unnecessary loops, so that the device
probe can complete early and proceed to parent port reset/reprobe process.
This can be reproduced on all kernel versions up to latest v5.6-rc2, but
after v5.5-rc7 the reproduce rate is dramatically lowered to 1/30 or less
while it was around 1/2.

net: deprecate eth_change_mtu, remove usage
With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.
v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86
