First, the crypto request completion handler contains a bug in that it fails to reset fs_done correctly after the request is completed. This is only a problem for asynchronous drivers. Second, some hardware drivers have input constraints which ZFS does not satisfy. For instance, ccp(4) apparently requires the AAD length for AES-GCM to be a multiple of the cipher block size, and with qat(4) the AES-GCM AAD length may not be longer than 240 bytes. FreeBSD's generic crypto framework doesn't have a mechanism to automatically fall back to a software implementation if a hardware driver cannot process a request, and ZFS does not tolerate such errors. The plan is to implement such a fallback mechanism, but with FreeBSD 13.0 approaching we should simply disable the use hardware drivers for now.
