ip does not in my man reading, offer similar performance. Is there a

Having viewed the web page at the URL cited by the original poster, to 
me, the original poster's question is "Why does this FreeBSD command not 
work on Linux?"

The command and the options, as stated in the original post, are in the 
exact format and syntax, specified explicitly for FreeBSD, and, not for 
Linux.

I have ifconfig installed and operational.

Did the original poster (and, the poster above), type
man ifconfig
to find what options are available on the distribution and version 
number of Linux, that they have installed?

The syntax as cited in the original post, is not available for the 
version of ifconfig that I have installed.

https://wiki.archlinux.org/title/Network_configuration/Wireless

to find the information that is sought.

Perhaps, both posters above, should try searching (with something like 
the Borg search engine named google), for how to find the relevant 
information on the distribution and version number of Linux, that they 
have installed, rather than complaining that a FreeBSD command does not 
work on it?

Sigh. Yes. There is a replacement. It is called ifconfig. Package
net-tools, as `apt-file search' has surely told you.

FWIW, I have *both* ifconfig and ip installed. I use *both*.

Unfortunately Tomas, neither util knows anything about radio's.  Someone 
just reminded me that iw is now the tool. I've found that /sbin/iw can 
output regulatory info, but the shorthand used is a bit opaque. From my 
one lonesome  wifi equipt rpi4b:
pi@rpi4:~ $ /sbin/iw reg get
global
country US: DFS-FCC
	(2402 - 2472 @ 40), (N/A, 30), (N/A)
	(5170 - 5250 @ 80), (N/A, 23), (N/A), AUTO-BW
	(5250 - 5330 @ 80), (N/A, 23), (0 ms), DFS, AUTO-BW
	(5490 - 5730 @ 160), (N/A, 23), (0 ms), DFS
	(5735 - 5835 @ 80), (N/A, 30), (N/A)
	(57240 - 63720 @ 2160), (N/A, 40), (N/A)

I have all of mine turned off and everything is wired to prevent the AH 
across the street from using my bandwidth to watch his porn. He had a 
utility on his cell phone capable of hijacking my radios. I hear he is 
back in the hotel for the 2nd time. Life in the neighborhood is much 
improved w/o him.

iw's output seems complete even if there is no radio, which the bpi's 
don't have, but from bpi54:
gene@bpi54:~$ /sbin/iw reg get
global
country 00: DFS-UNSET
	(2402 - 2472 @ 40), (6, 20), (N/A)
	(2457 - 2482 @ 20), (6, 20), (N/A), AUTO-BW, PASSIVE-SCAN
	(2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, PASSIVE-SCAN
	(5170 - 5250 @ 80), (6, 20), (N/A), AUTO-BW, PASSIVE-SCAN
	(5250 - 5330 @ 80), (6, 20), (0 ms), DFS, AUTO-BW, PASSIVE-SCAN
	(5490 - 5730 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN
	(5735 - 5835 @ 80), (6, 20), (N/A), PASSIVE-SCAN
	(57240 - 63720 @ 2160), (N/A, 0), (N/A)

note the 00: DFS-UNSET for country. the board doesn't even have a socket 
for a radio, but in practice its a supercharged rpi4b for $65 USD at 
alliexpress. I have yet to find something an rpi4b can do that the bpi's 
can't do. I have a sw problem with cups but I suspect its a software fix 
too.  Just got to find the magic mushroom. ;o)>

Take care & stay well, Tomas.
Cheers, Gene Heskett.

As far as I know they never did.

Yes, I think that one is your buddy.

Hm. As far as I understand the docs, this is telling you about
the regulatory database, i.e. how many dB your WiFi is supposed
to yell out at which freq depending on where your computer thinks
it is.

This exists independently of whether your hw is on or off, or
on whether you've got any radio hardware at all.

you did not post it all, if unset you can scan which is rx only, you 
cannot transmit until its set. That is regulatory edict all over this 
particular planet.

I don't know how freebsd handles this. In linux, setting the wrong
country can only reduce the performance you get, because it's likely
that the equipment you're using is already constrained by its
burned-in regulatory domain, and any limits (to TX power, channels,
etc) are combined. So you might as well get it right.

If the page you cited in your OP is up-to-date, then also bear in mind
that freebsd claims to use different country codes from the usual ISO
ones that linux uses (/usr/share/misc/countries.gz). One of them is
Australia, as it happens, a country partly running 8 hours ahead, like
wherever you are.

Cheers,
David.

Is it out of the question to actually set the regulatory domain to match
the country you're in?
