mac80211: handle power constraint/country IE better

Currently, mac80211 uses the power constraint IE, and reduces
the regulatory max TX power by it. This can cause issues if
the AP is advertising a large power constraint value matching
a high TX power in its country IE, for example in this case:

...
Country: US  Environment: Indoor/Outdoor
    ...
    Channels [157 - 157] @ 30 dBm
    ...
Power constraint: 13 dB
...

What happened here is that our local regulatory TX power is
15 dBm, and gets reduced by 13 dB so we end up with only
2 dBm effective TX power, which is way too low.

Instead, handle the country IE/power constraint IE combined
and restrict our TX power to the max of the regulatory power
and the maximum power advertised by the AP, in this case
17 dBm (= 30 dBm - 13 dB).

Also print a message when this happens to let the user know
and help us debug issues with it.

This means that device init can complete with commands pending, and

interfaces with priority 'j'. "bss_prio_tbl[j].bss_prio_cur" is
supposed to point to next interface every time the routine for
dequeuing the packet is called. This ensures that each interface
gets fair chance.

Currently we have AP and station interfaces with priority '0'.
Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should
alternately point to AP and station nodes. Since "bss_prio_cur"
is not correctly updated, for each packet picked for AP, two
packets are picked for station interface.

This patch fixes the problem by correctly updating "bss_prio_cur".

12 years agomwifiex: have same priority for AP and station traffic

mwifiex: have same priority for AP and station traffic

Currently AP interface has higher priority over station. Hence
separate entries are created in "adapter->bss_prio_tbl" for these
interfaces and station packet is dequeued only if there is not
packet in queue for AP. It is observed that ping for station
interface doesn't work if heavy traffic is running on AP.

The problem is fixed by having same priority for both the
interfaces. This patch also removes an extra initialisation
for "priv->bss_priority".
