Macros make it impossible to treat ifnet as an opaque type.
As such, it won't be possible to havr a single pre-compiled
driver that can work with different network stacks.

It's definitely been on our minds to make it possible to
use macros for performance reasons when ABI stability is
not a concern, but wanted to focus on ABI stability first.

FYI,
