Ok. Please do dig into it.
Do try to treat the regdomain code as a black box - input is
"what regulatory domain do we want" and the output is "a
list of channels and properties of those channels that we
currently program into net80211." Hopefully we don't have to
change the net80211 channel API!
This is the sort of information I'm looking for! So far all
I'm looking at is an XML file. Where would I find the
"regdomain code"?
(We really should write a page in the wiki about regdomain stuff.)
So, here's my suggestion:
* get freebsd with a supported wifi card
* look at what happens when you type "ifconfig wlan0 create
wlandev XXX"; and then "ifconfig wlan0 regdomain FCC3"
* .. see what it does with the channel programming in
src/sbin/ifconfig/ and src/lib/lib80211/
* Also 'ifconfig wlan0 list sta" and "ifconfig -v wlan0 list sta"
in src/sbin/ifconfig/ifieee80211.c look at
setdefregdomain(), setregdomain_cb(), print_channels() and
list_channels()
* print_channels() queries net80211 for the list of channels
* list_channels() calls it :-)
* setregdomain_cb() sucks in the lib80211 regdomain code, does a
bunch of hijinx, and then calls into net80211 using the
IEEE80211_IOC_REGDOMAIN ioctl to set the sku/country and the
channel list.

So much for limiting myself to XML parsing. I'll grab some source
files and take a look, I can code but might be too removed from
what's being done here to get my ahead around it. Thanks all.
Oh! It's ok! If this is too big a thing then we can look around for
other bits and pieces that need doing. :-)
I'd still like to get the regdomain stuff discussed!

No, I'm down - until I see what the code looks like of course. If it's
modular enough to be understood without too many adjacent systems I
might be alright. At present I'm less interested in changing the code
that operates on the XML file and more interested in a refactoring.
(Which will necessitate code changes, but I expect I'll be less involved
there.) I'm good at data design work, I'll try and stay in my lane.
