# v21 2026-07-21: HONEST labels (UCI now matches physical reality).
# Driver binds profiles by MacAddress match, NOT by l1profile order:
#   b0.dat (MacAddress=2.4G eeprom MAC) -> rax0 netdev (2.4G HW)
#   b1.dat (MacAddress=5G eeprom MAC)   -> ra0 netdev  (5G HW)
# v21 additionally swaps INDEX0_profile_path in l1profile.dat to
# "b1.dat;b0.dat", so l1dat_parser maps: idx=1 (ra0) -> b1.dat,
# idx=2 (rax0) -> b0.dat. Result: each UCI section writes the DAT that
# the driver actually binds to its phy, so UCI band/ssid can be honest:
#   idx=1 (ra0,  5G HW):  band=5g HE160 ch 36   ssid=ImmortalWrt-5G
#   idx=2 (rax0, 2.4G HW): band=2g HE40  ch auto ssid=ImmortalWrt-2.4G
# Kernel DBDC merge quirk (unchanged): VHT_BW / VHT_Sec80_Channel for
# ra0's slot are taken from b0.dat, so mtwifi_cfg still forces
# VHT_BW=2 + VHT_Sec80_Channel=155 into the band==2g profile.
# Validated live on v20 2026-07-21: ra0 2401Mbps HE160 ch36,
# rax0 HE40, DBDC_card0.dat identical to v20 working state.
