	Small send control queue message buffers are managed and reused by libie itself, bigger send buffers are consumed. All are 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. Rx buffers utilize page_pool. Pre-allocated DMA memory is used where possible. It reduces the driver overhead in handling memory allocation/free and message timeouts.
