On these PMDs, some of these algorithms do not support non byte aligned data.
For instance, for ZUC, the cipher algorithm doesn't support length in bits,
but the authentication algorithm does.
All test pass because in the tests we are doing encryption in bytes and then we mask off
the bits not used.
Wonder if we need two different flags for this, one for cipher and another one for authentication.
Maybe again this is not enough, since we should have a flag per algorithm... and starting with this flag is a step forward.
What do you think?

Thanks for looking into this!
Pablo
