The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Note that the RTL_VER_01 only support sw rx checksum only. Besides,

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.

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.

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.

field of a net_device structure or passed as the second argument to
netdev_set_default_ethtool_ops. These contexts are declared const, so

The RTL8153-AD supports a persistent system specific MAC address.
This means a device plugged into two different systems with host side
support will show different (but persistent) MAC addresses.
This information for the system's persistent MAC address is burned in when
the system HW is built and available under \_SB.AMAC in the DSDT at runtime.
This technology is currently implemented in the Dell TB15 and WD15 Type-C
docks. More information is available here:

There are some reasons for this. First, the settings are only

Second, the settings are independent with the others.
Last, the settings may take more time than the others. Leave
they in probe() or open() may delay the following flows.
