This allows to use the firmware monitor. This capability
uses a lot of contiguous memory (up to 64MB), so make its
usage module parameter dependent.
The driver will try to allocate as much contiguous memory
as possible downgrading its requirements until the
allocation succeeds.
Dump this data into the fw-error dump file when an error
happens.

The current sched scan channel configuration code
configures all the supported channels for scanning.
However, this can result in SYSASSERT in some cases,
when the configured channel is disabled.
Instead, configure only the channels given in the
req struct, and set the channel_count field appropriately.
While on it, change the code to use channel->hw_value
instead of recalculating the channel number.

However, this situation is normal after disconnect. If disconnect was while
heavy traffic load, lots of Tx packets will be dropped and this would

For performance monitoring, trace time intervals when Tx vring
is idle/not idle. Use CPU cycle counter for this, because jiffies is
too rough, and other precise time measurement methods involve
overhead while get_cycles() should be fast.
This used to provide some estimation for percentage when Tx vring
was idle, i.e. when hardware is under-utilized.
Estimation is not precise because of many reasons - CPU frequency scaling,
grt_cycles() may be per core etc. But still, it is good estimation
