v1->v2 1) Add the changes to the 18.11 release notes V1: Updated the rte ring C11 driver including the following changes 1) Synchronize the load and store of the tail to ensure the enqueue/dequeue operations are really completed before seen by the observers on the other sides. 2) Move the atomic load of head above the loop for the first iteration,it is not unnecessary and degrade performance for the other iteration as the head was loaded in the failure case of CAS.
