The "Interrupt Cause" register (VMXNET3_REG_ICR) is read-only.
Write accesses are ignored. Log them with as LOG_GUEST_ERROR
instead of aborting:

COLO-compare use the glib function g_queue_find_custom to dump
another VM's networking packet to compare. 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.

From: Rao Lei <lei.rao@intel.com>
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.

The vmnet framework is an API for virtual machines to read and write
packets.
The API allows a Guest OS interface to be in host mode or shared
mode. Interfaces in host mode can communicate with the native host
system and other interfaces running in host mode. In shared mode, the
network interface can send and receive packets to the Internet, the
native host, and other interfaces running in sharing mode.
Create separate netdevs for each vmnet operating mode:
- vmnet-host
- vmnet-shared
- vmnet-bridged

From: Vladislav Yaroshchuk <yaroshchuk2000@gmail.com>
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.

Fails to build on OSX Catalina:
../../net/vmnet-common.m:165:10: error: use of undeclared identifier
'VMNET_SHARING_SERVICE_BUSY'
case VMNET_SHARING_SERVICE_BUSY:
^
This constant only got added in macOS 11.0. I guess that technically
our supported-platforms policy only requires us to support 11 (Big Sur)
and 12 (Monterey) at this point, but it would be nice to still be able
to build on Catalina (10.15).
(Personally I would like Catalina still to work at least for a little
while, because my x86 Mac is old enough that it is not supported by
Big Sur. I'll have to dump it once Apple stops doing security support
for Catalina, but they haven't done that quite yet.)

Yes, it was only supported by the vmnet framework starting from
Catalyst according to
https://developer.apple.com/documentation/vmnet?language=objc.

Yes, there are some symbols from macOS >= 11.0 new backend
uses, not only this one, ex. vmnet_enable_isolation_key:

Sure, broken builds on old macOSes are bad. For this case I think
it's enough to disable vmnet for macOS < 11.0 with a probe while
configure build step. Especially given that Apple supports ~three
latest macOS versions, support for Catalina is expected to end
in 2022, when QEMU releases 7.0.
If this workaround is not suitable and it's required to support vmnet
in Catalina 10.15 with a subset of available features, it can be done.
But I'll be ready to handle this in approximately two-three weeks only.

I agree with Peter on this,
There's a lot of hardware running with Catalina. I think it's useful to
support it a little longer.

Right and Vladislav have disabled vmnet on the old versions.

Roman requested vmnet support for Catalina (10.15) also:
https://patchew.org/QEMU/20220111211422.21789-1-yaroshchuk2000@gmail.com/
After some thought I also found it important to support 10.15.
I've found a free hour to update patches and submit as v11
(still not displayed on Patchew for some reason).
Tested on Catalina 10.15 and Big Sur 11.5.
Built with no errors under Ubuntu 20.04 5.4.0-94-generic.
