show link state of HDLC netdev
Added by laforge over 3 years ago.
Updated over 3 years ago.
Description
We want to see the link state (up/down) of each HDLC netdev on which we have NS-VCs configured.
This should not be queried at the time of the "show" command, but we shoul continuously have an "ip link monitor" running, which will provide us with state change events. We then update some internal state member variables as well as log any state transitions.
- Status changed from New to In Progress
- Priority changed from Normal to High
- % Done changed from 0 to 50
- % Done changed from 50 to 80
From v4 of https://gerrit.osmocom.org/c/libosmocore/+/21458 onwards, the initial state is also dumped. The state nicely reflects in the VTY, and we get related log messages.
