This patchset introduces tdls funtionality without tdls peer uapsd
and tdls channel switching. Tdls is supported by qca6174 hardware
what is indicated by firmware through supported services.
Tdls station when authorized requires some parameters that are filled in
by rate control initialization. Because of that this patches contains
one patch for mac80211 which moves rate control initialization before
calling drivers station state with transition to authorized state.
v2:
-introduce tdls peer counter
-minor changes after review
Marek Puzyniak (3):
ath10k: make peer type configurable
mac80211: initialize rate control earlier for tdls station
ath10k: introduce basic tdls functionality
Michal Kazior (1):

There are a few different tx paths depending on
firmware and frame itself.
Creating a uniform decision will make it possible
to switch between different txmode easier, both
for testing and for future features as well.

* [PATCH v2 3/4] mac80211: initialize rate control earlier for tdls station

Currently when TDLS station in driver goes from assoc
to authorized state it can not use rate control parameters
because rate control is not initialized yet. Some drivers
require parameters already initialized by rate control when
entering authorized state. It can be done by initializing
rate control after station transition to authorized state
but before notifying driver about that.

* [PATCH v2 4/4] ath10k: introduce basic tdls functionality
2015-02-25 7:55 ` Marek Puzyniak
@ 2015-02-25 7:55 ` Marek Puzyniak
-1 siblings, 0 replies; 36+ messages in thread

To: linux-wireless, ath10k; +Cc: Marek Puzyniak, Michal Kazior, Marek Kwaczynski
This patch adds functions to enable/disable tdls
and to configure tdls peer station for tlv based firmware.
Tdls peer uapsd and tdls channel switching are not supported.
Transmitting tdls data frames works only for ethernet
type frames, that's why data addressed to tdls sta
is in ethernet format.
Tdls functionality for ath10k requires changes in mac80211
provided in patch:

* [PATCH v2 4/4] ath10k: introduce basic tdls functionality
@ 2015-02-25 7:55 ` Marek Puzyniak
0 siblings, 0 replies; 36+ messages in thread
From: Marek Puzyniak @ 2015-02-25 7:55 UTC (permalink / raw)
To: linux-wireless, ath10k; +Cc: Marek Kwaczynski, Marek Puzyniak, Michal Kazior
This patch adds functions to enable/disable tdls
and to configure tdls peer station for tlv based firmware.
Tdls peer uapsd and tdls channel switching are not supported.
Transmitting tdls data frames works only for ethernet
type frames, that's why data addressed to tdls sta
is in ethernet format.
Tdls functionality for ath10k requires changes in mac80211
provided in patch:
mac80211: initialize rate control earlier for tdls station

I don't like the idea of having another var in ath10k which isn't on
hotpath and can be derived from other structures/tools we already
have, i.e. ieee80211_iterate_stations_atomic(). You can use that to
implement ath10k_mac_tdls_num_peers(arvif).

With number of tdls peers being derived you won't be able to have this
kind of "recalc" logic anymore. I guess that's a good thing. You'll
need to call ath10k_wmi_update_fw_tdls_state() explicitly in
ath10k_sta_state() depending on context and numbers of peers.

I would `arg = {};` to make sure it's clean. Even if you're positive
you fill all `arg` members here it leaves it open for bugs sneaking in
when you extend the structure later on and forget to init new members
here as well.

It'd be nice (for me anyway) if you didn't send this in a series of
other patches I don't care about - I only ever saw this due to
patchwork.

Arik, you have a similar patch handling only NSS. Does this one look
fine to you, and would it solve the problem your other patch solved?

Well currently iwlmvm requires the NSS to be set before
IEEE80211_STA_ASSOC (earlier), so this doesn't help directly.
I could change mvm a bit to make it work, but I don't really see a
good reason for it :)
The patch looks good. Shouldn't introduce new issues (at least for iwlwifi).

Ok, thanks. Do you think it would be possible to move all of this before
ASSOC?
(if not, why not, and how is it that we have valid NSS if we don't have
the remaining data valid?)

We can probably move his rate_control_rate_init() to assoc, since we have this:
/*
* TDLS -- everything follows authorized, but
* only becoming authorized is possible, not
* going back
*/
if (set & BIT(NL80211_STA_FLAG_AUTHORIZED)) {
set |= BIT(NL80211_STA_FLAG_AUTHENTICATED) |
BIT(NL80211_STA_FLAG_ASSOCIATED);
mask |= BIT(NL80211_STA_FLAG_AUTHENTICATED) |
BIT(NL80211_STA_FLAG_ASSOCIATED);

I will try to prepare patch this week, if not I will wait for Arik's
proposition.
For ath10k rate control need to be initialised before moving to
STA_AUTHORIZED, so initialising rate control before STA_ASSOC is
perfectly fine.

Yes, mac80211 and driver patches need to be sent in separate series. I
will drop this series for now, please resend ath10k patches separetely.
AND please clearly document what mac80211 patches the ath10k patches
depend on.

Ok I did get to it today :)
With the attached patch applied, and the patch "mac80211: update TDLS
sta spatial streams before auth" reverted, I'm getting good
performance on iwlwifi.

Subject: [PATCH] mac80211: initialize rate control earlier for tdls station
Currently when TDLS station in driver goes from assoc
to authorized state it can not use rate control parameters
because rate control is not initialized yet. Some drivers
require parameters already initialized by rate control when
entering authorized state. It can be done by initializing
rate control after station transition to authorized state
but before notifying driver about that.

Cool. I think I'll apply this, but with the comment fixed to say
"associated" :)
But perhaps you can send this as a real patch to the list?
