Whenever the H/W path is enabled and traffic is in the binding state,
mac80211 is not aware of the traffic. Consequently, the LED does not
blink for that reason.

The ieee80211_tpt_led_trig_tx/rx functions are exported for the driver
so that we can report the tx and rx bytes from the driver when
the H/W path is being used.

suggest these should be in led.h since they are local to mac80211 and 
should not be directly invoked by clients of mac80211

why isn't this using CONFIG_MAC80211_LEDS??

why are you making these exported implementations instead of keeping 
them as inline in led.h?

what is the rationale for changing the signature, especially given that 
the first thing the implementations do is local = hw_to_local(hw)

We thought so. However, led.c has many same exported implementations,
including the local functions you suggested above. i.e.
__ieee80211_get_assoc_led_name() For the sake of consistency, we just
copy-pasted one of those functions. Do you want us to change this?

We want to make ieee80211_tpt_led_trig_rx() more generic so that it can
be called by driver as what he did in patch 6/6. But the
ieee80211_local can't be accessed other than mac80211 so he made this
change to use ieee80211_hw instead. Does that make sense?

The mac80211 patch should be first in the patchset to get more
visibility.
