[ANN] New firmware for Intel 7260 / 3160 - 22.212.9.0

[ANN] New firmware for Intel 7260 / 3160 - 22.212.9.0

[Emmanuel Grumbach]

Hi,

we have released a new firmware for 7260, 3160 and 7265 Intel WiFi devices.
This firmware is supported starting 3.14 kernel (when [2] will hit it).
We have a here quite a few bug fixes with a few new features
advertised by flags in the firmware file.
The most visible bug fix is a ping loss issue we had with certain APs
when using uAPSD.

The firmwares are available at [1].
I will send a pull request to linux-firmware.git soon.

The new firmware's version number is 22.212.9.0:

$ dmesg | grep loaded\ firmware
loaded firmware version 22.212.9.0 op_mode iwlmvm

Hi Ben,

You haven't pulled my tree yet, but I can't hold this any longer, so here you go. This pull request includes the previous one obviously.
I have here a new firmware for a new device: 7265, and an upgrade of the firmware for 7260 / 3160 / 7265 supported in 3.14.

Thanks!

Excellent! I've actually been watching almost-daily for a new firmware 
version, hoping it'd help out some of the issues I've been having with a 
7260 on a Cisco 802.11ac network. Primary issue is that my laptop would 
suddenly pick an AP with a very weak signal, and my connection would end 
up breaking to the point of being unusable until I reconnected (I think 
this is actually wpa_supplicant's job, not the card/driver/firmware, but 
since it worked fine on an old 6300 card on 802.11n I figure there has to 
be something with this card causing issues.) With a combination modern 
kernel (3.14.1+ or the 3.15 tree) and the previous firmware release, 
things were better, but I'd still have to reconnect maybe once or twice a 
day - and it never picked the 'best' AP (ie - my signal would always be 
relatively weak, even though there is an AP about 30 feet away from my 
desk). Installed this firmware with a build of 3.15, rebooted, and I've 
got a nice strong signal right off the bat:

signal:  	-55 [-55] dBm
signal avg:	-54 [-54] dBm
tx bitrate:	780.0 MBit/s VHT-MCS 8 80MHz short GI VHT-NSS 2
rx bitrate:	702.0 MBit/s VHT-MCS 8 80MHz VHT-NSS 2

It'll be interesting to see if it keeps on helping.  ;)

Thanks!

Hi,

I've just noticed that the firmware, as downloaded from both your git tree 
and from the wireless.kernel.org URL, reports that it is v23.214.9.0 --

$ dmesg | grep loaded\ firmware

Looks like a user reported the same thing in a RedHat bugzilla post:
https://bugzilla.redhat.com/show_bug.cgi?id=1087717 -- see comment #8.

I'm running 3.15.0-rc5 (Ubuntu's 'mainline' build), but I doubt that has 
anything to do with how the firmware reports its version.  ;)

Is the version number just wrong, or is this actually not the firmware you 
intended to release?

Thanks!

-Nate

So yeah  - the name of the directory / tarball isn't the same as the
version reported here. Sorry for that. No impact though.

Great, just wanted to make sure that it wasn't a bleeding-edge firmware 
that was unintentionally released or something like that.  ;)

Actually, I remember what happened - I started to prepare the
delivery, and then there were last minute fixes and I forgot to update
the title in the mail + tarball name.
But since Ben hasn't pulled yet, I might very well update it again
(with non critical fixes).
