Linux kernel static functions usb_string_sub() and usb_get_langid() were
made accessible to implement robust string rerieval.

Workers are only summoned by the manager or when there are no workers on
a work queue. In case a work in front of a work queue depends on a work
behind it, a deadlock may occur. To solve this Linux spawns a rescue
worker using timers. Timing of Linux based drivers is currently reworked
and not reliable. Therefore, we increase the number of workers that are
spawned from 1 to 3 per work queue in order to resolve possible
deadlocks.
Fixes#4762
Due to lacking hardware access the driver was test with one RTL8188EE
based device, namely [10ec:8179] (rev 01), only. As the access to the
PCI config space is restricted the driver loads the non power-saving
FW and the driver port is therefor only tested with that. The
accesses are documented should we choose to support them one way or
another later on.
The 'wifi.run' run script as well as Sculpt served as testing ground
where the driver worked fine so far.
Fixes#4714.
Lack of MSI-X support in DDE Linux causes a timeout when the Intel AX211
tries to call back into the driver while loading the PNVM file while
interrupts are still disabled.
With the patch picked up from QubesOS the card works on an X1 Nano G2:

Move 'linux-firmware' portion from 'dde_linux' into its own port,
while it is used by the upcoming new WLAN driver keep it in place
for the legacy one.

This commit contains a backport of commit [1] that deals with updating
the event ring dequeue pointer more often to prevent unnecessary
'Event Ring Full' errors.
[1] 'usb: host: xhci: update event ring dequeue pointer on purpose'
(dc0ffbea5729a3abafa577ebfce87f18b79e294b)
Fixes#4296.
Unfortunately, our current implementation of 'wmb()' doesn't seem to do what we
want it to do. On base-hw + imx6q_sabrelite, the write of bdp->cbd_sc seems to
get re-ordered after the write to txq->bd.reg_desc_active in the transmission
path of the contrib code. Due to this, the transmission of the packet is only
triggered the next time a packet is sent. However, we only quick-fix it by
enforcing the execution of the write with a volatile global read as we will
soon update the FEC NIC port with a new DDE approach anyway.
Fixes#4010
This patch takes advantage of block transfer interrupts on Intel XHCI
controllers which is used during isochronous transfers. Because of a bug
in hardware (see usb_host_isoc_bei.patch header), this feature has been
disabled for Intel leading to up to 8000 interrupts/s for isochronous
transfer causing severe CPU consumption on Genode. With this commit we
lower host driver consumption to normal levels.

This commit backports the Linux upstream commit (d4a6106) [*]
that introduces a check to prevent the sglist from being used
unconditionally.
[*] 'xhci: fix bounce buffer usage for non-sg list case'
Fixes#4116.
Thise driver supports USB LTE modems for Huawais' ME906s through MBIM
and provides a traditional Nic session. The "control" interface is a
Terminal session, which can be used via libmbim/mbimcli.
issue #3822
Move button-event reporting behind pointer-position update.
This is just a quickfix to restore correct pointer emulation with
dde_linux usb_drv. It does not change usb_hid_drv because the approach
is a questionable workaround of the current input event handling, which
reports events promptly on occurrence of inputs events and ignores
synchronization events completely. The original contrib code reported
the button press before absolute x and y positioning followed by a sync
event.
Issue #3019
Rather than removing the source files during the port preration, which
breaks preparing the port anew, they are now removed while creating
the src archive.
Fixes#2959.
Since we use the git repo by now remove all unnecessary ballast like
unused code and the git history. The will bring down the wifi_drv's
src archive to reasonable size again.
