- finished tx ack queue should be checked before new allocations
- packets which got not sent must be released in packet stream,
otherwise the network packet stream gets filled up and starves after a while
- rRegister for ack avail packets and process them concurrently to EMT-* threads
by nic_ep thread (thanks @Peter for the findings) + add synchronization.
- add sigh_ready_to_submit to network adapter to improve latency by notifying
the network model explicitly in case we had a full packet stream error case
(_retry resp. VERR_TRY_LATER)
Fixes#5045
This patch mirrors the interface of Sculpt's distant_runtime to the
sandboxed_runtime variant, allowing the configuration of xpos, ypos,
min_width, min_height, opaque, and background color.
Issue #5008
This patch moves the text-editing facility of app/text_area to a
text-area widget as part of the dialog library. This has two benefits.
First, it simplifies app/text_area by using the dialog API. Second, the
editor can now easily be reused by other dialog-API-based applications.
Fixes#5058
The 'Dynamic_array' utility is used by the text_area as internal
representation of text. As a prerequisite step of making the text
editing features generally available as a text-area widget, the
utility must become public.

This method allows for the inquiry of the current hovering state,
e.g., to suppress an update of the Wifi accesspoint list while
the list is hovered.

Issue #5053
Several DMA pools of the EHCI/UHCI USB host controller driver declare
that buffers should not cross 4K boundaries. If this property is not met
fatal errors like NMIs may happen during USB operation.
Discussed in issue #5000
Certain USB devices do not react anymore after an endpoint reset
in the use case of USB devices passed through to a virtual machine.
When investigating the only USB session client that needs the
flush transfers request - namely the Qemu xhci model used in
VirtualBox - there seems to be no need to reset the endpoint in fact.

USB devio splits large transaction into 16 KiB buffers in scatter-gather
lists. Unfortunately, this mechanism seems unreliable most certainly because
of issue #4809 "DDE Linux struct page object aliasing".
