this driver controls CESA unit as same as mvcesa, but uses DMA engines and does CBC operations, HMAC operations by hardware. about 2 kbytes of data are processed at one. supported algorithms are: - DES-CBC, 3DES-CBC, AES-CBC - HMAC-SHA1, HMAC-MD5 non-CBC algorithm such as AES-GCM is not supported by CESA's acceleration engine. mvcesa is still useful to implement such algorithms as combination of accelerated block cipher and software chaining.
