Currently the emulated EMAC for sun8i always traverses the transmit queue
from the head when transferring packets. It searches for a list of consecutive
descriptors whichs are flagged as ready for processing and transmits their payloads
accordingly. The controller stops processing once it finds a descriptor that is not
marked ready.
While the above behaviour works in most situations, it is not the same as the actual
EMAC in hardware. Actual hardware uses the TX_CUR_DESC register value to keep track
of the last position in the transmit queue and continues processing from that position
when software triggers the start of DMA processing. The currently emulated behaviour can
lead to packet loss on transmit when software fills the transmit queue with ready
descriptors that overlap the tail of the circular list.
This commit modifies the emulated EMAC for sun8i such that it processes
the transmit queue using the TX_CUR_DESC register in the same way as hardware.

Some mlx vdpa devices with kernels at least up to 5.11 currently present
0 as their MAC address. This is because they have not been
pre-configured with a MAC: they have a learning bridge and only learn
the MAC once guest is up. Kernel patches and tools to allow programming
the MAC from host are being developed. For now - since these
combinations exist in the field - let's detect zero mac and just try to
proceed with the mac from the qemu command line.
This makes the guest use this MAC to send packets in turn teaching
the MAC to the card, and things work.
TODO:
report the actual MAC from QEMU commad line in the info message.
TODO:
detect that a (non-zero) hardware MAC does not match QEMU command line
and fail init.

In failover_add_primary(), we search the id of the failover device by
scanning the list of the devices in the opts list to find a device with
a failover_pair_id equals to the id of the virtio-net device.
If the failover_pair_id is not found, QEMU ignores the primary
device silently (which also means it will not be hidden and
it will be enabled directly at boot).
After that, we search the id in the opts list to do a qdev_device_add()
with it. The device will be always found as otherwise we had exited
before, and thus the warning is never displayed.
Fix that by moving the error report to the first exit condition.
Also add a g_assert() to be sure the compiler will not complain
about a possibly NULL pointer.

failover_add_primary() calls qdev_device_add() and doesn't unref
the device. Because of that, when the device is unplugged a reference
is remaining and prevents the cleanup of the object.
This prevents to be able to plugin back the failover primary device,
with errors like:
(qemu) device_add vfio-pci,host=0000:41:00.0,id=hostdev0,bus=root.3,failover_pair_id=net0
(qemu) device_del hostdev0
We can check with "info qtree" and "info pci" that the device has been removed, and then:
(qemu) device_add vfio-pci,host=0000:41:00.0,id=hostdev1,bus=root.3,failover_pair_id=net0
Error: vfio 0000:41:00.0: device is already attached

Per MPC8548ERM [1] chapter 14.5.3.4.1:
When RCTRL.RSF is 1, frames less than 64 bytes are accepted upon
a DA match. But currently QEMU does the opposite. This commit
reverses the RCTRL.RSF testing logic to match the manual.
Due to the reverse of the logic, certain guests may potentially
break if they don't program eTSEC to have RCTRL.RSF bit set.
When RCTRL.RSF is 0, short frames are silently dropped, however
as of today both slirp and tap networking do not pad short frames
(e.g.: an ARP packet) to the minimum frame size of 60 bytes. So
ARP requests will be dropped, preventing the guest from becoming
visible on the network.
The same issue was reported on e1000 and vmxenet3 before, see:
commit 78aeb23ede ("e1000: Pad short frames to minimum size (60 bytes)")
commit 40a87c6c9b ("vmxnet3: Pad short frames to minimum size (60 bytes)")

At present net_checksum_calculate() blindly calculates all types of
checksums (IP, TCP, UDP). Some NICs may have a per type setting in
their BDs to control what checksum should be offloaded. To support
such hardware behavior, introduce a 'csum_flag' parameter to the
net_checksum_calculate() API to allow fine control over what type
checksum is calculated.
Existing users of this API are updated accordingly.

Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND(). But places where we must keep the list in order
by appending remain open-coded until later patches.
Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

The Xilinx ZynqMP CAN controller is developed based on SocketCAN, QEMU CAN bus
implementation. Bus connection and socketCAN connection for each CAN module
can be set through command lines.
Example for using single CAN:
-object can-bus,id=canbus0 \
-machine xlnx-zcu102.canbus0=canbus0 \
-object can-host-socketcan,id=socketcan0,if=vcan0,canbus=canbus0
Example for connecting both CAN to same virtual CAN on host machine:
-object can-bus,id=canbus0 -object can-bus,id=canbus1 \
-machine xlnx-zcu102.canbus0=canbus0 \
-machine xlnx-zcu102.canbus1=canbus1 \
-object can-host-socketcan,id=socketcan0,if=vcan0,canbus=canbus0 \
-object can-host-socketcan,id=socketcan1,if=vcan0,canbus=canbus1
To create virtual CAN on the host machine, please check the QEMU CAN docs:

An integer underflow could occur during packet transmission due to 'tx_len' not
being updated if SONIC_TFC register is set to zero. Check for negative 'tx_len'
when removing existing FCS.

While receiving packets via e1000e_write_packet_to_guest() routine,
'desc_offset' is advanced only when RX descriptor is processed. And
RX descriptor is not processed if it has NULL buffer address.
This may lead to an infinite loop condition. Increament 'desc_offset'
to process next descriptor in the ring to avoid infinite loop.
