It seems it can set it, but I don't see any command to print out
the current value?
Thanks,
Ben

This is pretty much last missing feature from iw.

Maybe that and current operating transfer rate? I can't
seem to find that anywhere other than 'iwconfig'...

iw wlan0 link shows that.

This does not work in adhoc mode:
# iw dev wlan0 info
Interface wlan0
ifindex 4
type IBSS
# iw dev wlan0 link
Not connected.

the TX rate is different for each station (and basically for each individual
packet too) so it does not make sense to show that for the "link" (what ever
"link" may mean in the context of ad-hoc...).
iw wlan0 station dump
can show you the last TX rate for each station, but again, the rate can and
will change on a per-packet basis.
there is no such thing as a "current transfer rate".

With iwconfig, we can set a fixed rate, shouldn't this be what we
expect to see as the 'rate'?
Speaking of, is there a particular reason why we still have to use
iwconfig to set the rate as well?

it only makes sense if you set a single fixed rate.

a TX bitrate mask has been added to iw in version 0.9.21:
commit 0db5d893ecf2ce4538af6fdcae3d94f2f83757e2
Author: Johannes Berg <johannes@sipsolutions.net>
Date: Fri Sep 24 17:44:07 2010 +0200
version 0.9.21
* transmit power support
* TX bitrate mask support
* more informative scan output
* make it build on old systems
you can use it like this, e.g.: "iw wlan0 set bitrates legacy-2.4 12 18 24"
this is much more flexible than the iwconfig way, as it allows a bitmap of TX
rates which can be used. again this is a reason why it does not make sense to
show a single TX bitrate, but i guess this TX bitmap could/should be shown
somewhere.
