Folks:
Perhaps this is due to me being a neophyte . . .
I notice that some of the structure have two different sets of functions.
For example, the ahash_alg structure has .init and then .base.cra_init.
What is the difference between the two?
Thanks

cra_init initialises a tfm object, while init is an operation
specific to hash algorithms --- it initialises the hash state.

I am still confused.
I have a hardware device whose driver has its own initialization API that
accepts the space for its own format for context as well as the mode.
Would I use that api for both the algorithm init and the context init
as the format of the context is unique to the hardware that I am using?
The docs don't explain this (unless there is documentation elsewhere
outside the kernel tree)
