SPROM rev 9 was discovered on 14e4:4331, it seems to have very similar
layout to rev 8 one. Use the same extracting function until we find some
differences.Signed-off-by: Rafał Miłecki

Add tx_conf array to save the current tx queues
configuration, and reconfig it on resume (ieee80211_reconfig).On resume, the driver is being reconfigured. Without
reconfiguring the tx queues as well, the driver might
configure the device to use wrong ac params (e.g. ps-poll
instead of uapsd).Signed-off-by: Eliad Peller

The first assignment of TX_CMD_FLG_SEQ_CTL_MSK for

The upper layer receives a pointer to an iwl_rx_mem_buffer. I would prefer the
upper layer to receive a pointer to an iwl_rx_packet, but this is impossible
since the Rx path needs to add the address of the page to the skb.
I may find a solution later.All the pre_rx_handler and notification code has been moved to the upper layer.

Since all the irq / tasklet is now handled in the transport layer, it should
give an API to ensure that all the irq / tasklet have finished running. This

PCIe doesn't provide any ISR registration API, whereas other buses do.
Hence, we need to move the tasklet and irq to the transport layer to allow this

When suspending with all netdevs down, the device
is stopped but we still call a number of driver
callbacks that the driver might not expect. The
same happens during resume, we might call a few
callbacks without starting the driver. Fix this
by checking open_count around more things and
exiting quickly if it is 0.Also, while at this I noticed that the coverage
class isn't reprogrammed after resume, so add
that.Signed-off-by: Johannes Berg

When the driver wants to pre-program the TKIP
RX phase 1 key, it needs to be able to obtain
it for the peer's TA. Add API to allow it to

For unicast the hardware sometimes reports MIC errors even though the
frame that it received actually contains a valid MIC - on some chips this
can happen frequently enough to trigger TKIP countermeasures.
Fix this issue by not reporting MIC errors for unicast frames with a
valid key, letting mac80211 validate the MIC instead.Additionally, strip the MIC for all frames that the hardware considers
valid to avoid wasting CPU cycles re-validating it.Signed-off-by: Felix Fietkau

Since we now have the necessary API in place to support
GTK rekeying, applications will need to know whether it
is supported by a device. Add a pseudo-trigger that is
used only to advertise that capability. Also, add some
new triggers that match what iwlagn devices can do.Signed-off-by: Johannes Berg

In WoWLAN, devices may use crypto keys for TX/RX
and could also implement GTK rekeying. If the
driver isn't able to retrieve replay counters and
similar information from the device upon resume,
or if the device isn't responsive due to platform
issues, it isn't safe to keep the connection up
as GTK rekey messages from during the sleep time
could be replayed against it.The only protection against that is disconnecting
from the AP. Modifying mac80211 to do that while
it is resuming would be very complex and invasive
in the case that the driver requires a reconfig,
so do it after it has resumed completely. In that
case, however, packets might be replayed since it
can then only happen after TX/RX are up again, so
mark keys for interfaces that need to disconnect
as "tainted" and drop all packets that are sent
or received with those keys.Signed-off-by: Johannes Berg

While 32 KHz sleep clock might provide some power saving benefits,
it is also a major source of stability issues, on OpenWrt it produced
some reproducible data bus errors on register accesses on several
different MIPS platforms.All the Atheros drivers that I can find do not enable this feature,
so it makes sense to leave it disabled in ath5k as well.Signed-off-by: Felix Fietkau
