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.

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.

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.

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.

Lan78xx driver accesses the PHY registers through MDIO bus over USB
connection. When performing a suspend/resume, the PHY registers can be
accessed before the USB connection is resumed. This will generate an
error and will prevent the device to resume correctly.
This patch adds the dependency between the MDIO bus and USB device to
allow correct handling of suspend/resume.

Minor conflict in drivers/s390/net/qeth_l2_main.c, kept the lock

Call napi_disable() twice would cause dead lock. There are three situations
may result in the issue.
1. rtl8152_pre_reset() and set_carrier() are run at the same time.
2. Call rtl8152_set_tunable() after rtl8152_close().
3. Call rtl8152_set_ringparam() after rtl8152_close().
For #1, use the same solution as commit 84811412464d ("r8152: Re-order
napi_disable in rtl8152_close"). For #2 and #3, add checking the flag
of IFF_UP and using napi_disable/napi_enable during mutex.

Both rtl_work_func_t() and rtl8152_close() call napi_disable().
Since the two calls aren't protected by a lock, if the close
function starts executing before the work function, we can get into a
situation where the napi_disable() function is called twice in
succession (first by rtl8152_close(), then by set_carrier()).
In such a situation, the second call would loop indefinitely, since
rtl8152_close() doesn't call napi_enable() to clear the NAPI_STATE_SCHED
bit.
The rtl8152_close() function in turn issues a
cancel_delayed_work_sync(), and so it would wait indefinitely for the
rtl_work_func_t() to complete. Since rtl8152_close() is called by a
process holding rtnl_lock() which is requested by other processes, this
eventually leads to a system deadlock and crash.
Re-order the napi_disable() call to occur after the work function
disabling and urb cancellation calls are issued.

The device supports macpassthru, but it failed to pass the test of -AD,
-BND and -BD. Simply bypass these tests since the device supports this
feature just fine.
Also the ACPI objects have some differences between Dell's and Lenovo's,
so make those ACPI infos no longer hardcoded.

Support the firmware of PHY NC which is used to fix the issue found
for PHY. Currently, only RTL_VER_04, RTL_VER_05, and RTL_VER_06 need
it.
The order of loading PHY firmware would be
RTL_FW_PHY_START
RTL_FW_PHY_NC
RTL_FW_PHY_STOP
The RTL_FW_PHY_START/RTL_FW_PHY_STOP are used to lock/unlock the PHY,
and set/clear the patch key from the firmware file.

The struct fw_type_1 is used by MAC only, so rename it to a meaningful one.
Besides, adjust two messages. Replace "load xxx fail" with "check xxx fail"

This device is sold as 'ThinkPad USB-C Dock Gen 2 (40AS)'.
Chipset is RTL8153 and works with r8152.
Without this, the generic cdc_ether grabs the device, and the device jam
connected networks up when the machine suspends.

As soon as the netdev is registers, the kernel can start using the
interface. If the driver connects the MAC to the PHY after the netdev
is registered, there is a race condition where the interface can be
opened without having the PHY connected.
Change the order to close this race condition.

The serial state information must not be embedded into another
data structure, as this interferes with cache handling for DMA
on architectures without cache coherence..
That would result in data corruption on some architectures

This patch supports loading additional firmware file through
request_firmware().
A firmware file may include a header followed by several blocks
which have different types of firmware. Currently, the supported
types are RTL_FW_END, RTL_FW_PLA, and RTL_FW_USB.
The firmware is used to fix some compatible or hardware issues. For
example, the device couldn't be found after rebooting several times.
The supported chips are
RTL_VER_04 (rtl8153a-2.fw)
RTL_VER_05 (rtl8153a-3.fw)
RTL_VER_06 (rtl8153a-4.fw)
RTL_VER_09 (rtl8153b-2.fw)

When the MAC address is supplied via device tree or a random
MAC is generated it has to be written to the asix chip in
order to receive any data.
Previously in 9fb137aef34e ("net: usb: ax88179_178a: allow
optionally getting mac address from device tree") this line was
omitted because it seemed to work perfectly fine without it.
But it was simply not detected because the chip keeps the mac
stored even beyond a reset and it was tested on a hardware
with an integrated UPS where the asix chip was permanently
powered on even throughout power cycles.
