CCS_START_NETWORK is declared in drivers/net/wireless/rayctl.h with the
comment Values for cmd. status is previously compared to
CCS_COMMAND_COMPLETE, which is declared in the same file with the comment
Values for buffer_status. Finally, it is possible at this point that cmd
is CCS_START_NETWORK, because it is compared to that value in an enclosing
switch that has CCS_START_NETWORK as one of two case labels around this code.

Move clear of CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ to be after nearby

removed it entirely, but just making sure in case someone removes the

Follow-up to "update write pointers for all tx queues after wakeup"; that
patch changed iwl_irq_tasklet_legacy(), but not iwl_irq_tasklet(), so
newer devices were not covered.
Comments from original patch:
Wakeup interrupt has been updating write pointers (indexes, actually) only
for tx queues 0-5. This is adequate just for 3945, but inadequate for other
devices, all of which have more tx queues. Now updating all tx/command queues,
so device can be aware of all new tx and host commands enqueued while
device was asleep.
This can potentially improve data traffic bandwidth and/or latency.

Take advantage of device's auto-increment for SRAM reads to eliminate extra
write address accesses.
Grab/release NIC access before/after entire read sequence, rather than for
each read individually.
After a quick check of dmesg logs, this seems to double Event Log dump speed,
reducing from about 20 milliseconds to about 10 milliseconds for 512 entries
using 3945.

If device provides bad values for Event Log parameters (due to being asleep
or SRAM corruption, etc.), the size can be very, very large (e.g. 0xa5a5a5a5),
which can flood system log.

When I added that code setting the swq_id, I evidently
did not understand the distinction between FIFO and TX
queue yet and added code to compare a queue ID and a
FIFO number, which is bogus.
However, the code there need not be this specific, it
can just set all queues to the identity mapping which
will be overwritten by the aggregation queue code. As
a bit of defensive coding, don't assign an swq_id to
the command queue so that if we ever use it for frames
we notice quickly.

The fourth queue (command queue) is already activated in
the loop above that also maps it to the command FIFO and
therefore doesn't need to be marked as activated again.
Also change the TODO comment to be accurate -- we need
to initialise the _queues_, not FIFOs, and map them to
device FIFOs.

This patch rearranges the SIT DF bit handling using the new IPIP DF
code. The only externally visible effect should be the case where
PMTU is enabled and the MTU is exactly 1280 bytes. In this case the
previous code would send packets out with DF off while the new code
would set the DF bit. This is inline with RFC 4213.
