New ath10k CT firmware released.

New ath10k CT firmware released.

[Ben Greear]

I have uploaded the latest CT version of the ath10k firmware.

http://www.candelatech.com/ath10k.php

This firmware fixes bugs in raw-tx mode, though probably only
non-encrypted frames can be sent in this manner, and it requires
an out-of-tree patch from Michal Kazior to make it work:

This firmware also significantly improves association times when using
more than one vdev.  This, requires an additional kernel patch:

http://dmz2.candelatech.com/git/gitweb.cgi?p=linux-3.17.dev.y/.git;a=commitdiff;h=a9756b6e2efffbec4101dbe81e9d6a2c503239ff;hp=5bfa637376c352fc17c56afc7b1d2e752750162c

And, you may want the near-by patches that allow disabling some
logging, especially if using serial console.

There is also a small fix to max-nss logic in the firmware rate-control,
but I am not sure this is required.  It _is_ required that you use
currently-out-of-tree patches if you want anything other than 3x3 station
connecting to 3x3 AP to work properly with ath10k.

As always, I am interested to know how people are using
the CT firmware, and I would welcome any help with getting
even basic support (such as reserved feature flags)
for this firmware in the upstream kernel.

Thanks,
Ben

I was a bit too clever it seems....  I have to be more careful about disabling
the ch reservation when there are no vdevs active, I think.

Hope to have it fixed shortly.

Thanks,
Ben

Looks like firmware was fine, so it remains unchanged.  But, the driver patch has to
be more careful and only disable ch reservation if we currently have an active channel.

This patch (on top of the one linked above) seems to work well:
