Understood, I'll remove this line.

Because the way to load a PHY driver module can't handle multiple
modules with the same phy id (a NIC driver loads a PHY driver module).
There is no machinism to specify which PHY driver module should be
loaded when multiple PHY modules have the same phy id (as far as I know).
The Kconfig file would be like the following. AX88796B_RUST_PHY
depends on AX88796B_PHY so the description of AX88796B_PHY is enough?
I'll add the name of the module.
config AX88796B_PHY
tristate "Asix PHYs"
help
Currently supports the Asix Electronics PHY found in the X-Surf 100
AX88796B package.
config AX88796B_RUST_PHY
bool "Rust reference driver"
depends on RUST && AX88796B_PHY
default n
help
Uses the Rust version driver for Asix PHYs.

Not sure. Is it possible? If we allow both modules to be built, I
guess it's possible though.

Ah, I'll add.
