netlab wrapper for tc

[ipspace]

It would be nice to have a wrapper for some reasonably-simple tc CLI (comcast comes to mind) to introduce latency/jitter/delay/drops into topology links.

The wrapper should be similar to netlab capture (it can probably reuse 90% of the code) -- find the interface, execute external command to configure tc parameters

Any ideas for the CLI command we can use instead of tc @jbemmel @ssasso @ddutt @hellt

netem - see https://containerlab.dev/manual/impairments/
(still tc command)

I once proposed to support declarative impairments (like a WAN link with 100ms latency) but this never made it into the tool afaik

Could be a plugin that adds the tc settings to link

We could also set the link impairment parameters in the topology file ;)
