Tailscale exit-node UDP GRO persistence systemd unit (Raspberry Pi)

Tailscale exit-node: persist UDP GRO config across reboots

Companion to https://x.com/joedevon/status/2049142808762835189. The Raspberry Pi's eth0 interface ships with rx-udp-gro-forwarding off, which throttles WireGuard's UDP throughput. The article shows the one-line ethtool fix that applies to the current boot. This systemd unit makes the fix survive reboots.

Install (run this whole block on the Pi)

sudo tee /etc/systemd/system/tailscale-eth0-gro.service > /dev/null <<EOF

Description=Tailscale: configure UDP GRO forwarding on eth0 for exit-node throughput
