Without suspend/resume functionality in the USB driver the USB core
will disconnect and reconnect the DLN2 port and because the GPIO
framework does not yet support removal of an in-use controller a
suspend/resume operation will result in a crash.
This patch provides suspend and resume functions for the DLN2 driver
so that the above scenario is avoided, if the host controller does not
drop VBUS during suspend, since in this case the device state is
preserved.
We chose not implemented reset_resume so that if the host controller
does drop VBUS the resume path will go through above the
disconnect/reconnect process since it is probably better to fix the
GPIO framework disconnect issue then to save and restore the device
state for every driver.

The driver loads the 2 CPU sections, then it needs to let
the firmware know to start the authentication of the
sections. This is done by writing the relevants bits to
FH_UCODE_LOAD_STATUS.
For CPU1, the driver sets the lower 16 bits. For both CPUs,
the driver sets all the 32 bits.

* fix network-manager which was broken by the previous changes
* fix delete-station events, which were broken by me making the

* fix a timer left running during suspend in some race conditions
that would cause an annoying (but harmless) warning
* (less important, but in the tree already) remove 80+80 MHz rate
reporting since the spec doesn't distinguish it from 160 MHz;
as the bitrate they're both 160 MHz bandwidth
If the firmware sends spontaneous DTS notfications with the
temperature (indicated in a TLV), we can ignore the temperature we get
in the RX statistics notifications. This prevents potentially

notifications with temperature equal to 0 that happens from time to

When we want to trigger an NMI in the device, we need to set
bit 7 and not bit 0. However, older firmwares don't register
to the interrupt issued by bit 7. Use bit 7 first so that
the correct interrupt will be issued hoping that the firmware
will react. To be on the safe side, set bit 0 in case the
firmware didn't register to the proper interrupt.

A new host command can be used to configure the scheduler
instead of accessing the scheduler's registers from the
driver. This is easier and less error prone since accessing

Use only basic dwell time (10 ms for active scan and 110 for passive),
regardless of the number of the probes and the band, if it is
supported by the FW. The FW will add 3 ms for each probe sent and 10
ms for low band channels.
Add a TLV flag to indicate such support in FW.

Fragmented scan should be applied for all channels, passive and active.
When scanning on passive channels the firmware uses frag_passive_dwell
to define the maximum continuous scan time before returning to the
operating channel. On active channels max_out_time is the parameter
used by the firmware to define the maximum time allowed out of the
operating channel. Since active channels' scan should also be fragmented
set max_out_time equal to frag_passive_dwell.
In addition:
- Set max_out_time and suspend_time if the firmware doesn't support
fragmented scan to avoid unexpected behavior.
- Adjust max_out_time for second level of scan precedence.
