This crate contains the driver trait necessary for adding embassy-net support
for a new hardware platform.
If you want to use embassy-net with already made drivers, you should depend on the main embassy-net crate, not on this crate.
If you are writing a driver, you should depend only on this crate, not on the main embassy-net crate.
This will allow your driver to continue working for newer embassy-net major versions, without needing an update,
if the driver trait has not had breaking changes.
See also embassy-net-driver-channel, which provides a higer-level API
to construct a driver that processes packets in its own background task and communicates with the embassy-net task via
packet queues for RX and TX.
This crate can run on any executor.
