This check was added in #38110, when we still used from-netdev for the wireguard interface. But as #38077 was developed in parallel, it looks like the change was accidentally dropped when introducing the dedicated from-wireguard program.

@smagnani96 👋 does this make sense, or did we have some reason for not carrying the fragmentation-check over? The impact is probably fairly minimal ...

Yep, it does make sense, dropping these bits was unintentional 😅
