1//! SDIO Protocol implementations live here.
2//!
3//! NOTE: this is not a traditional SDIO protocol that you may be familiar with
4//! this is very specific to the nintendo's CAT-DEV environment. It is also
5//! split over two TCP ports.
6//!
7//! The only part that "has a protocol" too is the control port. The data port
8//! is literally just transferring files around.
