Listen on all interfaces

[ebroto]

The parameter "-i" is now optional and we listen on all interfaces by default.
The interface is shown in the connections table.

I've changed the read timeout for the datalink channel from 1 ns to 2 ms because I realized (before the changes) that we were using quite some CPU there. In my computer it went from taking consistently over 10% of one CPU to ~2%. I think it should be enough to handle the traffic and to keep the application responsive to the "quit" key. Let me know if you find it appropriate!

Closes #16

Hey @ebroto - really great work as usual! Just a couple of minor issues and I'd be excited to go forward and merge this.

[imsnif]

Also, forgot to mention, the timeout increase works great for me too and I'm very happy about the CPU performance - so thanks, let's go with this.

[imsnif]

Hey, just one more thing with the break syntax and we're good to go with this.

Got caught by clippy in the CI, happy that it works :)

On it

[imsnif]

Cool - so I think this is good to merge once the tests pass. Definitely good to know the new CI stuff is working. :)

Feel free to merge, I'll publish to the various outlets over the weekend (at some point I'll have to automate this).

Hey @ebroto - I'm in the process of releasing 0.5.0 right now and it mainly includes your work. I'd like to announce it on twitter so it gets a little exposure: do you use twitter? I'd very much like to give you credit. :)

[ebroto]

Thanks!! I appreciate the intention but I'm not on twitter. I usually read the subreddit but mainly lurking, so a mention would be more than enough :)
