There have been some discussions about it. At present, there is no implementation of these discussions. There are some intricacies and some restructuring of cgd required to take advantage of hw crypto, in particular it needs to grow a means to asynchronously schedule encryption and decryption, and probably a kernel thread context to facilitate this. These changes would bring a few other benefits as well, but the current simplicity of cgd is also a desirable feature.
It's not clear that it would even be faster. cgd encrypts one sector at a time, and that is going to translate into a lot of setup overhead for a crypto accelerator card.
