We were toggling the wrong bit when we reset the device,
fix that. Moreover, since the reset can take time, we need
to wait before we set the rfkill interrupt. Not doing so
can be racy since the driver is enabling the rfkill
interrupt while the device is resetting which will clear
all the registers including the CSR_INT_MASK.
This can basically lead to a situation where we don't
enable the rfkill interrupt. If that happens, the user will
not be able to re-enable the device when de-asserting
rfkill.

Our firmware scheduler suffers from false wake-up on 500 time units.
that is if the dtim interval exceeds 500 time units, the fw wakes up,
understands that the next wake-up event is still ahead, and if this event
is more than 10msec in the future - goes back to sleep, otherwise - stay
awake. For example, say that the beacon interval is 101 and the dtim
period is 5, the dtim interval is 101 x 5 = 505, and we will stay awake
for those extra 5msec.
So on the one hand the dtim interval should be congruent to the beacon
interval times the dtim period, and on the other should minimize
the false wake-ups event.
This change applies only to D0/D3 power modes.

This patch removes the interframe spacing time workaround from at86rf230
driver and use the mac802154 one. The interframe spacing time differs at
at86rf212 and channel setting. This patch fix this handling which is also
a new workaround and should be moved into mac802154 while channel
setting.

This patch adds a new interframe spacing time handling into mac802154
layer. Interframe spacing time is a time period between each transmit.
This patch adds a high resolution timer into mac802154 and starts on
xmit complete with corresponding interframe spacing expire time if
ifs_handling is true. We make it variable because it depends if
interframe spacing time is handled by transceiver or mac802154. At the
timer complete function we wake the netdev queue again. This avoids
new frame transmit in range of interframe spacing time.
For synced driver we add no handling of interframe spacing time. This
is currently a lack of support in all synced xmit drivers. I suppose
it's working because the latency of workqueue which is needed to call
spi_sync.

This patch removes the invalid max frame retries check from driver
layer. This is already handled by nl802154 framework. Also the IEEE
802.15.4 standard doesn't allow a frame retries setting above 7. This
seems to be valid for the at86rf230 transceiver but the chip running out
of spec then. We only allow settings according 802.15.4 right now.

On some platforms, system goes out of memory during heavy
Rx traffic with our USB chipsets.
In case of SDIO/PCIe, after receiving 50 packets in Rx queue
we stop processing interrupts till packets pending fall below
low threshold i.e 20. We don't have similar logic for USB,
so if host platform is slow, we would hit a case where firmware
keeps on pushing packets at high speed than driver/kernel can
process.
We will stop submitting URBs for Rx data when pending packet
count reaches high threshold and restart them when enough
packets are consumed to solve the problem.
