Commit "vbox: avoid uncaught nic Empty_ack_queue exception" introduced a
performance regression due to packet retransmission because of faulty
GSO segment handling. As fixing the GSO handling is fairly complex, we
disable GSO until a fix was developed.

For Windows guests, it's crucial to configure the paravirtualization
provider in .vbox6 like follows. Otherwise, the TSC calibration fails
(issue #4726) and the CPU frequency (in task manager) is bogus.
<Paravirt provider="HyperV"/>
Fixes#4726
Check 'pv == nullptr' in 'ShClSvcImplWriteData' and return
VERR_INVALID_POINTER if invalid (as is done, for example, in the X11
implementation).

This networking scenario is useful for analysing and optimizing the
interplay of the VFS, libc, TCP/IP, and the NIC router. It downloads a
file via fetchurl from lighttpd, both of which are hosted on a virtual
network.
Issue #4697
200 TSC ticks for max measurement duration can get too small on platforms
with high TSC frequencies (e.g., >3GHz) and low CPU frequencies often
caused by HWP configurations. Therefore, we express the measurement
duration in NS (not ticks) and calculate max duration ticks using the
TSC frequency. This way the max duration becomes independent of the TSC
frequency.

If `select_from_ports` is evaluated lazily, we might miss a port during
the dependency check. A way to prevent this is to use the `:=` operator.

During initialization _handle_link_state may be called concurrently from EMT and
"nic_ep" (signal handler). Therefore, sent signal to "nic_ep" instead of calling
_handle_link_state from EMT thread.
issue #4632
With the increase of MAXPHYS, the rump kernel requests a contiguous
allocation of 2101248 bytes, which exceeds the allocator's block size of
2 MiB.
Error: backend allocator: Unable to allocate memory (size: 2101248 align: 12)
The patch avoids this corner case by increasing the allocator's block
size to 4 MiB.
Fixes#4613
The `with_sub_node` method is renamed to `with_optional_sub_node` to
better reflect that the non-existence of a sub node with the desired type is
ignored.
At the same time, the new `with_sub_node` now takes a second functor that is
called when no sub node of the desired type exists.

Instead of having a generic "virt_qemu" board use "virt_qemu_<arch>" in
order to have a clean distinction between boards. Current supported
boards are "virt_qemu_arm_v7a", "virt_qemu_arm_v8a", and
"virt_qemu_riscv".
