Yes, I believe that could be right, *a* world regulatory domain looks
indeed enforced, the USA one only, which is pre-set default inside
EEPROM registries device, isn't it?

AFAIK, also brcmsmac needs at least 2 firmware files to operate, without
those nothing works.
Isn't it the same concept?

If that was a suggestion about to purchase a bcm43224 or any other
Broadcom Corp. product, isn't really convincing, seen the overall
support quality Customers are experiencing in here...
About my capture file, in the case it was really incomplete someone
could have informed me at least a year ago.
But anyway no respectable QA Testing team needs a purchasing Customer to
help in verifying such enormous issue, isn't it?

Really, *TWO* men? Are you kidding? Is that how much Broadcom Corp.
values the Linux community?
Needles to remind, even if Linux users don't pay for the OS license as
Windows do, they do pay allright for any Broadcom hardware they
purchase!
Internet startups which sell a button on internet, they have Dev and QA
team 5 times bigger than that!
I sense a very gross capacity and resource planning competence issue in
here.
I kindly ask you, please forward that mail to your higher Managers, on
my personal behalf, Thanks.
