I'm looking forward to more XDP + eBFP, VPP, or FD.io based firewall and routing solutions as I think those are where we'll see the next big improvement in networking at. I'm hoping to get my hands on some NICs that support XDP offloading. I can see the future homelabbers leveraging SmartNICs and/or DPUs for routing/firewall applications instead of using large big iron custom ASIC switches.
