beatzaplentyandClaude Sonnet 4.6 4be064572d feat(tailscale): enable UDP GRO forwarding on subnet router uplink
Check NixOS configurations / eval-hosts (pull_request) Successful in 10m42s
Adds a oneshot systemd service that sets ethtool rx-udp-gro-forwarding on
and rx-gro-list off on the default-route interface at boot, silencing
Tailscale's warning about suboptimal UDP GRO forwarding on subnet routers.
Interface is discovered dynamically via `ip route get` so it works on all
platforms regardless of NIC naming.

beatzaplentyandClaude Sonnet 4.6 e4b335be23 refactor(tailscale): rename exit-node to subnet-router; drop --advertise-exit-node
Check NixOS configurations / eval-hosts (pull_request) Successful in 10m37s
The host was always intended as a LAN subnet router (--advertise-routes),
not a full exit node (--advertise-exit-node). Rename every trace of
"exit-node" to "subnet-router" and remove the --advertise-exit-node flag
from extraSetFlags; the operator supplies --advertise-routes at first
tailscale up and Tailscale persists it in state across reboots.

Routing sysctls (useRoutingFeatures = "server"), openFirewall, and
trustedInterfaces = ["tailscale0"] are still required for subnet routing
to work, so the module is kept — just correctly named.
