net: usb: r8152: Use linkmode helpers for EEE

Make use of the existing linkmode helpers for converting PHY EEE
register values into links modes, now that ethtool_keee uses link
modes, rather than u32 values.

Rework determining if EEE is active to make is similar as to how
phylib decides, and make use of a phylib helper to validate if EEE is
valid in for the current link mode. This then requires that PHYLIB is
selected.

net: usb: make USB_RTL8153_ECM non user configurable

This refixes:

commit 7da17624e7948d5d9660b910f8079d26d26ce453
nt: usb: USB_RTL8153_ECM should not default to y

In general, device drivers should not be enabled by default.

which basically broke the commit it claimed to fix, ie:

commit 657bc1d10bfc23ac06d5d687ce45826c760744f9
r8153_ecm: avoid to be prior to r8152 driver

Avoid r8153_ecm is compiled as built-in, if r8152 driver is compiled
as modules. Otherwise, the r8153_ecm would be used, even though the
device is supported by r8152 driver.

this commit amounted to:

drivers/net/usb/Kconfig:

+config USB_RTL8153_ECM
+ tristate "RTL8153 ECM support"
+ depends on USB_NET_CDCETHER && (USB_RTL8152 || USB_RTL8152=n)
+ default y
+ help
+ This option supports ECM mode for RTL8153 ethernet adapter, when
+ CONFIG_USB_RTL8152 is not set, or the RTL8153 device is not
+ supported by r8152 driver.

drivers/net/usb/Makefile:

-obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o r8153_ecm.o
+obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o
+obj-$(CONFIG_USB_RTL8153_ECM) += r8153_ecm.o

And as can be seen it pulls a piece of the cdc_ether driver out into
a separate config option to be able to make this piece modular in case
cdc_ether is builtin, while r8152 is modular.

While in general, device drivers should indeed not be enabled by default:
this isn't a device driver per say, but rather this is support code for
the CDCETHER (ECM) driver, and should thus be enabled if it is enabled.

And when we say "removed" we can just hide it from what's prompted

this way we don't bring back Marek's complaint.

Side note: these incorrect defaults will result in Android 13
on 5.15 GKI kernels lacking USB_RTL8153_ECM support while having
USB_NET_CDCETHER (luckily we also have USB_RTL8150 and USB_RTL8152,
so it's probably only an issue for very new RTL815x hardware with
no native 5.15 driver).

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)

The current behavior is clearly intentional, giving a warning when
a user picks a configuration that won't do anything good. The only
reason for even addressing this is that I'm getting close to
eliminating all 'randconfig' warnings on ARM, and this came up
a couple of times.

My workaround is to not even build the module when none of the
configurations are enable.

Alternatively we could simply remove the #warning (nothing wrong
for compile-testing), turn it into a runtime warning, or
change the Kconfig options into a menu to hide CONFIG_USB_NET_CDC_SUBSET.

usbnet: New driver for QinHeng CH9200 devices

There's a bunch of cheap USB 10/100 devices based on QinHeng chipsets. The
vendor driver supports the CH9100 and CH9200 devices, but the majority of
the code is of the if (ch9100) {} else {} form, with the most significant
difference being that CH9200 provides a real MII interface but CH9100 fakes
one with a bunch of global variables and magic commands. I don't have a
CH9100, so it's probably better if someone who does provides an independent
driver for it. In any case, this is a lightly cleaned up version of the
vendor driver with all the CH9100 code dropped.
