Bugs surrounding this issue can manifest in a variety of ways but frequently pend_cmd is over written. Simultaneously executing commands can result in a misconfigured device or DPDK sleeping in a thread for 2 second. Despite this limitation, vf commands may be executed from both iavf_dev_alarm_handler() in a control thread and the applications main thread. This is trivial to simulate in the testpmd application by creating a bond of vf's in active backup mode, and then turning the bond off and then on again repeatedly. Previously [1] was proposed as a potential solution, but this commit did not resolve all potential issues concerning the admin queue and has been reverted from the stable branch. I propose adding locks until a more complete solution is available.
