Description
I've been hacking up a DAHDI driver for the icE1usb, which is currently available [only] from https://github.com/osmocom/dahdi-linux/tree/laforge/icE1usb
The current code seems to be working fine- it survives manual USB unplug/replug tests
- it survives hundreds of rmmod/insmod cycles
- it causes no CRC errors when used with e1-prbs-test over multiple hours
- no reporting of errors via DAHDI APIs (alarms, crc erorrs, ...)
- no reporting of link status via DAHDI APIs (RED/YELLOW/BLUE/...)
- no control over local/remote clock usage
Checklist
- host repository on osmocom.org
- RED alarm on LOS
- YELLOW alarm
- BLUE alarm
- error counters/stats via DAHDI APIs
- CRC4 enable/disable
- select local/remote clock source via DAHDI

icE1usb: Support reporting of RED alarm via DAHDI infrastructure
We get loss-of-framing and loss-of-signal notification via USB interrupt
transfers. Let's make use of this information to tell the DAHDI core
[and ultimately the user] about this.

icE1usb: Support TX configuration (CRC4 on/off, loopback, timing source)
This adds support of configuring the icE1usb TX configuration via the
standard DAHDI mechanisms.
As for YELLOW alarm, there's a WIP patch for the firmware in https://gerrit.osmocom.org/c/osmo-e1-hardware/+/26706.

reporting of remote alarms as YELLOW alarm has been added in https://github.com/osmocom/dahdi-linux/commit/7043d45f77ee8fe633e5181f7f7ae22e4e051071
git repo is now [also] at https://git.osmocom.org/dahdi-linux/
remaining issues have been split into #5382 and #5381, so this ticket can be cloed. The DAHDI driver exists and works reliably, AFAICT.
