This works half way decent enough to make the LED status change visibly
in case the physical link is disconnected. However, we will generate a
storm of USB interrupt endpoint messages if we leave this on

We don't really have an idea of the analog signal level and hence
no true LOS detection. However, we can check the Rx clock tick counter
to detect if there is at least still any kind of signal at all or not.

AIS is an all-1 bit-pattern which is used by intermediate equipment
to indicate that the link somewhere upstream is lost.

So far we started on altsetting 0->1 transition, but we didn't stop
on the inverse 1->0 which typically happens when the host software
(osmo-e1d) stops.

This introduces a number of vendor-specific control requests for
configuration of the icE1usb from the host software.

Those clear bits are only set once at start-up and then later
explicitly. They shouldn't be stored with the user configuration
in state variables.

Whenever Rx is aligned, the green LED is permanently on.
Whenever Rx is not aligned, the green LED is blinking.
What's missing is to check for E1 clock ticks and turn the LED off
completely if there are no clock ticks.

This should enable the host to detect discontinuities, and also know
when a multiframe starts.

The position indicates where we are in terms of frame and multiframe.
The related code was ported over from e1-tracer.

A value of '1' means _no_ CRC4 error observed. We got that right
in the receive side, but not in the transmit side so far

When encoding the CRC bit for Frame number 0 and 8 in the multiframe,
we must first move the CRC4 into those of the last SMF.

This resembles what we do for other firmware targets, such as simtrace2,
osmo-ccid-firmware, etc.
As we have multiple different firmware, hardware, gateware projects in
this repository, and they each may have separate tags, we now require
that there are project specific tags. So for example, tags with a
prefix of icE1usb-fw for the firmware versions.
symlinks for easy use by scripts etc. are generated, always pointing to
the last-built versioned filename.

This was broken when moving the design to non-hacked multi channel
E1.

This was never used and doesn't really belong here, this was just
an example descriptor in the original firmware this is based on.
