Hi Greg,
The management of the relationships between the keying routines and the encryption/decryption routines for AES_NI operations and for the programmed code are entirely separate. In both cases the 'inf' field in the contexts is managed by the keying routines all of which set the 'inf' field to zero ('inf' is a union and cx->inf.l is set to zero). As you found, AES_NI does not use the inf.b[2] field in managing the relationship between keying and encryption/decryption.
The distinction between encryption and decryption contexts managed using inf.b[2] applies only to situations when AES_NI is not used.
No user management of anything within encryption/decryption contexts is necessary (indeed it would be dangerous!).

I had missed that aes_inf was a union; thanks for pointing that out.
