The latest generation hardware requires IO CQ (completion queue) descriptors memory to be aligned to a 4K. It needs that feature for the best performance. Allocating unaligned descriptors will have a big performance impact as the packet processing in a HW won't be optimized properly. For that purpose adjust ena_dma_alloc() to support it. It's a critical fix, especially for the arm64 EC2 instances.
