This includes the HAL routines to setup, enable/activate/disable spectral
scan and configure the relevant registers.
This still requires driver interaction to enable spectral scan reporting.
Specifically:
* call ah_spectralConfigure() to configure and enable spectral scan;
* .. there's currently no way to disable spectral scan... that will have
to follow.
* call ah_spectralStart() to force start a spectral report;
* call ah_spectralStop() to force stop an active spectral report.
The spectral scan results appear as PHY errors (type 0x5 on the AR9280,
same as radar) but with the spectral scan bit set (0x10 in the last byte
of the frame) identifying it as a spectral report rather than a radar
FFT report.
Caveats:
* It's likely quite difficult to run spectral _and_ radar at the same
time. Enabling spectral scan disables the radar thresholds but
leaves radar enabled. Thus, the driver (for now) needs to ensure
that only one or the other is enabled.
* .. it needs testing on HT40 mode.
Tested:
* AR9280 in STA mode, HT/20 only
TODO:
* Test on AR9285, AR9287;
* Test in both HT20 and HT40 modes;
* .. all the driver glue.

FDT headers can't be included if the kernel is compiled without
FDT support, due to dependence on generated kobj headers. BERI
supports both FDT and non-FDT kernels.

"ed-argument-digit" (i. e. command 0) was incorrectly used
instead.
This bug comes from the original sources imported in 1994
and has been confirmed in upstream NetBSD.

(as used in AM335x SoC for BeagleBone).
Among other things:
* Watchdog reset doesn't hang the driver.
* Disconnecting cable doesn't hang the driver.
* ifconfig up/down doesn't hang the driver
* Out-of-memory no longer panics the driver.
Known issues:
* Doesn't have good support for fragmented packets
(calls m_defrag() on TX, assumes RX packets are never fragmented)
* Promisc and allmulti still unimplimented
* addmulti and delmulti still unimplemented
* TX queue still stalls (but watchdog now consistently recovers in ~5s)
* No sysctl monitoring
* Only supports port0
* No switch configuration support
* Not tested on anything but BeagleBone

mount, which means that is must not be called while the snaplock is
owned. The vfs_write_resume(9) does call the function as the
VFS_SUSP_CLEAN() method, which is too early and falls into the region
still protected by snaplock.
Add yet another flag for the vfs_write_resume_flags() to avoid calling
suspension cleanup handler after the suspend is lifted, and use it in
the ffs_snapshot() call to vfs_write_resume.
