Optional reuse port for old devices

[Hanssen0]

Hi!

I'm trying to add mDNS service for an old device (specifically, Kindle PW2 from 2013). It runs a Linux 3.0.35 kernel, which doesn't support SO_REUSEPORT.

I added a feature flag on my fork and tested that it works, so I plan to open a PR here.

Before that, my question is, do you prefer to control this feature manually by devs or silently ignore the error and then continue if it fails?

Thanks for opening this!

I would prefer the devs control this feature manually.
