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.
This patchset is RFC because it based on patchset from Michal:
ath10k: add multi-channel support
which is still under 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):
ath10k: unify tx mode and dispatch

Function in mac.c should have a `ath10k_mac_` prefix.

Anyway I see little point in having this wrapper function just to call
wmi function?

The ath10k_mac_ prefix is missing: ath10k_mac_tdls_peer_update().

I would `xxx = {}` to make these are zero-ed. Right now you pass
uninitialized vars from the stack..

Once you `= {}` it's probably redundant to zero each structure member like that.

What if you have 2 TDLS peers? If you disconnect the first one you'll
disable TDLS on the entire vdev while the other peer is still
connected. I don't think that's desired.
Perhaps the per-vdev TDLS command can be called in
add_interface()/remove_interface()? If that's not possible I guess you
could use ieee80211_iterate_stations_atomic() to look if there's still
at least one TDLS peer present.

It's meaningless to call tdls_peer_update() if assoc failed. From
practical standpoint fw is probably dead at that point and subsequent
commands will timeout. You can `goto exit`.

Why not use `len` for alloc_skb()?

Could be const struct on these _args.

These comments seem redundant and don't introduce any extra info..

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.

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

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.

Peer type was hardcoded to default value.
For future implementation it is required
to make is configurable.
