This driver supports two Microchip USB-Ethernet controllers:
LAN7800 USB 3.1 to 10/100/1000 Mbps Ethernet
LAN7515 USB 2 to 10/100/1000 Mbps Ethernet with built-in USB hub
The LAN7515 is the Ethernet controller on the Raspberry Pi 3B+.
At present there is no datasheet for the LAN7515, but it is effectively
a USB 2 hub combined with a LAN7800 controller. A comprehensive LAN7800
datasheet is at http://www.microchip.com/wwwproducts/en/LAN7800.
This driver is based on the structure of the smsc(4) driver which
supports Microchip/SMSC's LAN95xx family. (Microchip acquired SMSC
in May 2012.) The Linux lan78xx driver served as a reference for some
functionality and registers.
The 'muge' driver name comes from "Microchip USB Gigabit Ethernet".
I made some style adjustments and minor edits to Arshan's submission.
It will be connected to the build after additional review and testing.
Thanks to Microchip for providing a number of Evaluation Boards (EVBs)
for development and testing.

In smsc_phy_init function, when the driver was trying to reset PHY, it
didn't poll for the correct bit (BMCR_RESET) to be cleared. Instead, it
anded it with MII_BMCR (which is 0), so it just exited the loop.
This issue was fixed in Linux in commit d94609200069.

device-side (and only device-side) "virtual USB serial adapters" - the
ones you can get with an OTG-capable board - as consoles. It boils down
to adding the device name to kern.console sysctl, although doing that
requires jumping through some hoops. It doesn't change the actual
operation of those virtual devices. The point is to make it possible
for init(8) to recognize them as console devices and to launch getty(8)
for them, when configured as "onifconsole" in ttys(5). The point of
that, in turn, is to add such entries to the default ttys(5), so that
init(8) will launch gettys for device-side "virtual serial adapters",
but not for actual USB serial dongles.

OF_getprop_alloc takes element size argument and returns number of
elements in the property. There are valid use cases for such behavior
but mostly API consumers pass 1 as element size to get string
properties. What API users would expect from OF_getprop_alloc is to be
a combination of malloc + OF_getprop with the same semantic of return
value. This patch modifies API signature to match these expectations.
For the valid use cases with element size != 1 and to reduce
modification scope new OF_getprop_alloc_multi function has been
introduced that behaves the same way OF_getprop_alloc behaved prior to
this patch.

opt_compat.h is mentioned in nearly 180 files. In-progress network
driver compabibility improvements may add over 100 more so this is
closer to "just about everywhere" than "only some files" per the
guidance in sys/conf/options.
Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of
sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h
is created on all architectures.
Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the

This detaches it from provider device, so single device driver can export
multiple different phys. Additionally, this allows phy to be subclassed to
