A similar observation: With OpenWrt 15.05.1, after booting, dmesg
output contains driver messages related to regulatory domain
changes and final (I hope) settings:

One can easily see region changing from 'unset' over 'FCC' to 'ETSI'.

With current LEDE, however, these messages are completely missing,
making it harder to trust radio obeying regulatory rules.  I mean, what
is the rationale for this change (as well as that subject of the other
mail)?
