Thanks!
I'll try to update everything in the post when I'm not so jet-lagged.

Generate a libbpf.pc file at build time so that users can rely
on pkg-config to find the library, its CFLAGS and LDFLAGS.

This patch implements accessors for the QCA8337 MDIO access
through the MDIO_MASTER register, which makes it possible to
access the PHYs on slave-bus through the switch. In cases
where the switch ports are already mapped via external
"phy-phandles", the internal mdio-bus is disabled in order to
pre
This patch updates the qca8k's binding to document to the
approach for using the internal mdio-bus of the supported
qca8k switches.

In the example, the phy at phy@0 is clashing with
the switch0@0 at the same address. Usually, the switches
are accessible through pseudo PHYs which in case of the
qca8k are located at 0x10 - 0x18.

Currently the Phy driver's link_change_notify callback is called
whenever the state machine is run (every second if polling), no matter
whether the state changed or not. This isn't needed and may confuse
users considering the name of the callback. Actually it contradicts
its kernel-doc description.
Replace open coded netdev_() macros.

The debug prints of network operations will look better if network

the actual hardware when more than one is installed on the system.

Eliminate some boilerplate code by using module_spi_driver() instead of
