mwl8k: handle 5 GHz legacy rate bitmaps in firmware commands
Whenever mac80211 gives us a legacy rate bitmap in the context of the
5 GHz band, we need to remember to shift the bitmap left by 5 positions
before giving it to the firmware, as the firmware follows the bitmap
bit assignment of the 2.4 GHz rate table even if we're on the 5 GHz
band, and the 2.4 GHz rate table includes five non-OFDM rates at the
start that are not valid in the 5 GHz band.

mwl8k: properly set receive status rate index on 5 GHz receive
The mwl8k firmware uses indices into the 2.4 GHz band rate table for
the receive descriptor channel field even if the packet was received
on a 5 GHz channel, while mac80211 expects an index into the 5 GHz
band rate table when packets are received on the 5 GHz band, which
presents a mismatch as the 5 GHz band rate table lacks the five
non-OFDM rates that the 2.4 GHz rate table starts with.
To handle this properly, we need to substract 5 from the rate index
field if the packet was received on a 5 GHz channel (and was not
received at an MCS rate).

mac80211: check uapsd state for dynamic power save
To make U-APSD client mode effective, we must not wake up from dynamic power
save when transmitting frames. So if dynamic power save is enabled, it needs
check the queue the transmitted packet is in and decide if we need to wake
up or not.
In a perfect world, where all packets would have correct QoS tags, U-APSD
enabled queues should not trigger wakeup from power save. But in the real
world, where very few packets have correct QoS tags, this won't work. For
example, if only voip class has U-APSD enabled and we send a packet in voip
class, but the packets we receive are in best effort class, we would receive
the packets with the legacy power save method. And that would increase
latencies too much from a voip application point of view.
The workaround is to enable U-APSD for all qeueus and still use dynamic ps
wakeup for all other queues except voip. That way we can still save power
with a voip application and not sacrifice latency. Normal traffic (in
background, best effort or video class) would still trigger wakeup from
dynamic power save.

mac80211: flush workqueue before calling driver ->stop() method
Since commit "mwl8k: handle station database update for AP's sta entry
via ->sta_notify()", mwl8k every now and then gets a command timeout
when ifconfig'ing a STA interface down. This turns out to be due to
mwl8k_stop() being called while the work queue item that was scheduled
by mwl8k_sta_notify() to remove the STA entry for the associated AP is
still queued, and the former disables interrupts so that when the
latter eventually runs, a command completion interrupt is never seen.
Fix this by changing ieee80211_stop_device() so that the workqueue is
flushed before drv_stop() is called, instead of doing it the other way
around as is done now. (As ->stop() is allowed to sleep, there isn't
any reason for drivers to queue work from within it.)

mwl8k: keep TX_DONE interrupt masked while transmit reclaim is running
By making use of the CLEAR_SEL feature of the mwl8k host interface
interrupt controller, we can keep the TX_DONE interrupt source masked
while the transmit reclaim tasklet is running (NAPI style) without
having to touch the interrupt controller's interrupt mask register
when entering or exiting polling mode, and without having to do any
more register reads/writes than we do now.
When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading
the interrupt status register will clear the TX_DONE status bit if
it was set, allowing it to be set again if a new TX_DONE event arrives
while we are running the TX reclaim tasklet, but such a new event will
then not trigger another PCI interrupt until a zero is written to the
TX_DONE interrupt status register bit.
I.e., if we write a zero to the TX_DONE interrupt source bit in the
interrupt status register when the TX reclaim tasklet thinks it's
done, a PCI interrupt will be triggered if a new TX_DONE event arrived
from the hardware between us deciding that there is no more work to do
and re-enabling the TX_DONE interrupt source, thereby avoiding the
classic NAPI poll mode exit race that would otherwise occur.

mac80211: fix a few work bugs
Kalle and Lennert reported problems with the new work
code, and at least Kalle's problem I was able to trace
to a missing jiffies initialisation.
I also ran into a problem where occasionally I couldn't
connect, which seems fixed with kicking the work items

Finally, also add some sanity checking code to verify
that we're not adding work items while an interface is

cfg80211: Store IEs from both Beacon and Probe Response frames
Store information elements from Beacon and Probe Response frames in
separate buffers to allow both sets to be made available through
nl80211. This allows user space applications to get access to IEs from
Beacon frames even if we have received Probe Response frames from the
BSS. Previously, the IEs from Probe Response frames would have
overridden the IEs from Beacon frames.
This feature is of somewhat limited use since most protocols include
the same (or extended) information in Probe Response frames. However,
there are couple of exceptions where the IEs from Beacon frames could
be of some use: TIM IE is only included in Beacon frames (and it would
be needed to figure out the DTIM period used in the BSS) and at least
some implementations of Wireless Provisioning Services seem to include
the full IE only in Beacon frames).
The new BSS attribute for scan results is added to allow both the IE
sets to be delivered. This is done in a way that maintains the
previously used behavior for applications that are not aware of the
new NL80211_BSS_BEACON_IES attribute.

In AP mode, mac80211 was unconditionally using the lowest rate for

mac80211: fix ieee80211_change_mac() to use struct sockaddr
Setting the mac address from user space was buggy. For example, when
executing this command:
ip link set wlan0 address 00:1f:df:88:cd:55
mac80211 used the address 01:00:00:1f:df:88 instead. It was shifted two
bytes.
The reason was that the addr (type of void *) provided to
ieee80211_change_mac() is actually of type struct sockaddr, not just the
mac address array. Also the call to eth_mac_addr() expects the address to
be struct sockaddr.

mac80211: fix a warning related to pointer conversion to u64 cookie

Fix it by casting the pointers to unsigned long instead. This makes the
compiler happy again.
Compile-tested only.
