rust: phy: use VTABLE_DEFAULT_ERROR

2024-01-27T14:28:00+00:00

Since 6.8-rc1, using VTABLE_DEFAULT_ERROR for optional functions
(never called) in #[vtable] is the recommended way.

Note that no functional changes in this patch.

rust: phy: use `srctree`-relative links

2024-01-27T14:26:48+00:00

The relative paths like the following are bothersome and don't work
with `O=` builds:

//! C headers: [`include/linux/phy.h`](../../../../../../../include/linux/phy.h).

This updates such links by using the `srctree`-relative link feature
introduced in 6.8-rc1 like:

//! C headers: [`include/linux/phy.h`](srctree/include/linux/phy.h).

rust: net::phy add module_phy_driver macro

2023-12-15T09:35:50+00:00

This macro creates an array of kernel's `struct phy_driver` and
registers it. This also corresponds to the kernel's
`MODULE_DEVICE_TABLE` macro, which embeds the information for module
loading into the module binary file.

A PHY driver should use this macro.

rust: core abstractions for network PHY drivers

2023-12-15T09:35:50+00:00

This patch adds abstractions to implement network PHY drivers; the
driver registration and bindings for some of callback functions in
struct phy_driver and many genphy_ functions.

This feature is enabled with CONFIG_RUST_PHYLIB_ABSTRACTIONS=y.

This patch enables unstable const_maybe_uninit_zeroed feature for
kernel crate to enable unsafe code to handle a constant value with
uninitialized data. With the feature, the abstractions can initialize
a phy_driver structure with zero easily; instead of initializing all
the members by hand. It's supposed to be stable in the not so distant
future.
