Looks good to me. Little nit on the CHANGELOG. Can you update it now that you have a new parameter added ?

Good catch @AurelienFT , I've updated it in 1127c7200

We shouldn't merge this PR before https://github.com/FuelLabs/fuel-core/pull/2131

Plus, let's wait for my review as well, since maybe we need to clean up some other logic

How's this coming?

Thanks for resurfacing this @MitchTurner it got lost in the ether with the mainnet whirlwind of changes.

I've resolved the conflicts so it's ready for review again. I know @xgreenx wanted to look into it again but the changes imo are relatively low surface - I've upgraded our libp2p version + introduced connection limit options.

Hello @maschad,

As you mentionned that @xgreenx wanted to look again we will wait him before merging this but I can already re-approve as a first approver. However before approving the conflicts should be resolved, are you ok to resolve them ? Or we can do it for you, if you prefer :)

Thanks again for this PR.

Thanks @AurelienFT I've gone ahead and resolved the conflicts.
