Currently, OpenCrypto consumers can request asynchronous dispatch by setting a flag in the cryptop. (Currently only IPSec may do this.) I think this is a bit confusing: we (conditionally) set cryptop flags to request async dispatch, and then crypto_dispatch() immediately examines those flags to see if the consumer wants async dispatch. The flag names are also confusing since they don't specify what "async" applies to: dispatch or completion. Add a new KPI, crypto_dispatch_async(), rather than encoding the requested dispatch type in each cryptop. crypto_dispatch_async() falls back to crypto_dispatch() if the session's driver provides asynchronous dispatch. Get rid of CRYPTOP_ASYNC() and CRYPTOP_ASYNC_KEEPORDER(). Similarly, add crypto_dispatch_batch() to request processing of a tailq of cryptops, rather than encoding the scheduling policy using cryptop flags. Convert GELI, the only user of this interface (disabled by default) to use the new interface. Add CRYPTO_SESS_SYNC(), which can be used by consumers to determine whether crypto requests will be dispatched synchronously. This is just a helper macro. Use it instead of looking at cap flags directly. Fix style in crypto_done(). Also get rid of CRYPTO_RETW_EMPTY() and just check the relevant queues directly. This could result in some unnecessary wakeups but I think it's very uncommon to be using more than one queue per worker in a given workload, so checking all three queues is a waste of cycles.
