When Rx/Tx queue was being created with DevX the allocated doorbell record size was only uint64_t. That was definitely less than size of CPU cacheline and it might have happened the doorbell records attached to different queues handled by different cores were allocated within same cacheline. It might have caused the contention on doorbell record writing. This patch extends the allocated memory size for doorbell record to cacheline size.
