Annoying error message: ieee80211 phy0: invalid plcp cck rate (0)

Greetings Fellow Forumers!

I have an annoying issue caused by (I think) the firmware (carl9170) necessary to allow my USB NIC to work.  The issue itself is that this message will pop up on my console and TTY:

ieee80211 phy0: invalid plcp cck rate (0)

I have searched the forums and found nothing (as of yet). I have, however, found some sparse information on the Internet but it isn't very helpful.  Most of what I've read describes the behaviour itself (the error messages spamming the screen) and developers who figured out that it is the firmware causing this behaviour.  I have yet to find information about how to solve this issue and stop the error from repeating itself ad nauseum.  What I have read so far also hasn't cast any illumination about the underlying cause as to why the error message is being printed in the first place.

LSHW shows this about the USB device itself:

bus info: usb@2:2
logical name: wnet
capabilities:
	ethernet,
	Physical interface,
	Wireless-LAN
configuration:
	broadcast: yes
	driver: [i]carl9170[/i]
	driverversion: 3.15.8-1-ARCH
	firmware: 1.9.6
	ip: 192.168.1.74
	link: yes
	multicast: yes
	wireless: IEEE 802.11abgn

   
If all I can do is suppress this message I'll be happy with that.  Admittedly, though, I'll need a hint or two about how to do that.

I have the same issue and found nothing useful. Does anyone have tips?
