# 99-custom-config - Apply TR3000-specific defaults on first boot
# Sets LAN IP, WiFi SSID/htmode/uapsd, dnsmasq, IPv6 RA, turboacc BBR
# Runs once (uci-defaults scripts auto-delete after running)
#
# v29 2026-07-22: HONEST labels. UCI idx=1=5g config (driver maps
# band=5g content to the 5G PHY whatever netdev it is this boot).
# idx=2=2g config (maps to 2.4G PHY). ra0/rax0 netdev binding is
# random per boot but physical broadcast always correct (band-content
# invariant). LuCI Overview shows iwinfo truth. Edit forms show UCI
# config. Do NOT use LuCI Save and Apply (triggers wifi reload);
# reboot to apply wireless changes.

# ===== Firewall: prepare for MSS clamp via hotplug =====
# fw4 reload wipes hotplug MSS clamp rules; the 30-mss-clamp hotplug
# re-adds them on every iface ifup. No static config needed here.
