ehea: Fix synchronization between HW and SW send queue When memory is added to / removed from a partition via the Memory DLPAR mechanism, the eHEA driver has to do a couple of things to reflect the memory change in its own IO address translation tables. This involves stopping and restarting the HW queues. During this operation, it is possible that HW and SW pointer into these queues get out of sync. This results in a situation where packets that are attached to a send queue are not transmitted immediately, but delayed until further X packets have been put on the queue. This patch detects such loss of synchronization, and resets the ehea port when needed.
