By removing the queue_index check, it is\npossible for multiple napi instances to access the Rx ring at the same time,\nwhich will result in a corrupted ring state which can lead to a crash when\nflushing the rings in __xsk_flush(). This can happen when the linked list of\nsockets to flush gets corrupted by concurrent accesses. A quick and small fix\nis not possible, so let us revert this for now."
