But this function always start find from the queue->head(here is the newest packet), It will reduce the success rate of comparison. So this patch reversed the order of the queues for performance.

charset="utf-8" From: Rao Lei This patch is to improve the logic of QEMU main thread sleep code in qemu_chr_write_buffer() where it can be blocked and can't run other coroutines during COLO IO stress test. Our approach is to put filter_send() in a coroutine. In this way, filter_send() will call qemu_coroutine_yield() in qemu_co_sleep_ns(), so that it can be scheduled out and QEMU main thread has opportunity to run other tasks.

charset="utf-8" From: Vladislav Yaroshchuk Interaction with vmnet.framework in different modes differs only on configuration stage, so we can create common `send`, `receive`, etc. procedures and reuse them. vmnet.framework supports iov, but writing more than one iov into vmnet interface fails with 'VMNET_INVALID_ARGUMENT'. Collecting provided iovs into one and passing it to vmnet works fine. That's the reason why receive_iov() left unimplemented. But it still works with good enough performance having .receive() implemented only. Also, there is no way to unsubscribe from vmnet packages receiving except registering and unregistering event callback or simply drop packages just ignoring and not processing them when related flag is set. Here we do using the second way.
