> bookkeeping support for control queue messages
>
> From: Phani R Burra <[email protected]>
>
> All send control queue messages are allocated/freed in libie itself
> and tracked with the unique transaction (Xn) ids until they receive
> response or time out. Responses can be received out of order,
> therefore transactions are stored in an array and tracked though a
> bitmap.
>
> Pre-allocated DMA memory is used where possible. It reduces the driver
> overhead in handling memory allocation/free and message timeouts.
