This was inherited from iwlwifi, which drives devices supported by both
iwn(4) and iwm(4) in FreeBSD. In iwm(4) _mvm is meaningless, so remove
it. OpenBSD made the same change a long time ago. No functional change
intended.

Though we don't otherwise use firmware's offload capabilities, we need
to set this flag when the MAC header's size isn't a multiple of four.

This is the multiqueue receive code required for 9000-series chips.
Note that we still only configure a single RX queue for now. Multiqueue
support will require MSI-X configuration and a scheme for managing a
global pool of RX buffers.

* Remove outdated notifications IWM_SCAN_ABORT_CMD,
IWM_SCAN_START_NOTIFICATION and IWM_SCAN_RESULTS_NOTIFICATION.
* Remove unused enum iwm_scan_complete_status.
* Use the updated FW Api version 3 of struct iwm_scan_results_notif.
* No functional change, since struct iwm_scan_results_notif is never
accessed in iwm at the moment.

* If device family is 8000 then iwm_pcie_load_cpu_sections()

* Factor out iwm_handle_rxb() function from iwm_notif_intr().
* Removing the IWM_FH_RCSR_CHNL0_RX_CONFIG_SINGLE_FRAME_MSK flag allows
the device to put multiple frames (both command responses and 80211
frames) into a single RX buffer.
* Uses m_copym() to split up the receive buffers when multiple 80211
frames are received in one RX buffer. The effect is basically the same
as when using m_split(), but we want to keep the original mbuf around
when calling iwm_mvm_rx_rx_mpdu() to make error handling a bit easier
for now.
* Contains a small optimization to avoid the m_copym() when only a single
80211 frame is received in one RX buffer (i.e. matching the existing
behaviour).

* The DEVICE_POWER_FLAGS_CAM_MSK flag was removed in the upstream iwlwifi
in Linux commit ceef91c89480dd18bb3ac51e91280a233d0ca41f.
* Add sc_ps_disabled flag to struct iwm_softc, which corresponds to
mvm->ps_disabled in struct iwl_mvm in Linux iwlwifi.
* Adds a hw.iwm.power_scheme tunable which corresponds to the power_scheme
module parameter in Linux iwlwifi. Set this to 1 for completely
disabling power management, 2 (default) for balanced powermanagement,
and 3 for lowerpower mode (which does dtim period skipping).
* Imports the constants.h file from iwlwifi as if_iwm_constants.h.
* This doesn't allow changing the powermanagement setting while connected,
also one can only choose between enabled and disabled powersaving with
ifconfig (so switching between balanced and low-power mode requires
rebooting to change the tunable).
* After any changes to powermanagement (i.e. "ifconfig wlan0 powersave" to
enable powermanagement, or "ifconfig wlan0 -powersave" for disabling
powermanagement), one has to disconnect and reconnect to the accespoint
for the change to take effect.

IWM_UCODE_TLV_FLAGS_PM_CMD_SUPPORT,

IWM_UCODE_TLV_FLAGS_D3_CONTINUITY_API,

* Adds IWM_DEBUG_TEMP debug message type, for printing messages related
to temperature sensors and thermal/TDP infos.
* The firmware regularly sends us DTS measurement notifications, so just
print the temperature value as a debugging message.
(Adrian's addition):
* Eventually this can be used by the driver to limit transmit rate / power to
try and do some thermal throttling.

* sc->sc_nvm becomes sc->nvm_data and is now a pointer instead of an
inlined struct.
* Add sc->eeprom_size and sc->nvm_hw_section_num configuration values to
struct iwm_softc.
* For now continue to avoid negative error return-values, and use pointer
variables for some return values, as before.
* Continue to omit LAR (location aware regulatory) related code as well.
Tested:
* Intel 7260, STA mode (2GHz)

* No functional change.

The wantresp field in struct iwm_rx_data has never been used for anything,
so we can just delete it.
Apparently struct iwm_sf_cfg_cmd was compiled correctly (using a 32bit
value to represent the enum), but it still seems like a very bad idea to use
an enum type in a __packed struct.

When building a Tx Command for management frames, we are lacking
a check for action frames, for which we should set a different
pm_timeout. This cause the fw to stay awake for 100TU after each
such frame is transmitted, resulting an excessive power consumption.

Move some declarations to if_iwmreg.h.
Remove iwm_fw_alive(); just call iwm_post_alive() directly.
Simplify iwm_mvm_add_sta().
Return timeout error from iwm_apm_init().
Print a message when init (i.e. boot) firmware fails to load.
Remove some commented-out code which wouldn't compile anyway.
Move iwm_mvm_tx_fifo to if_iwmreg.h to match better where Linux puts it.

There are still several bugs, but I've been using it for a while now.
Thanks to all the testers and to Adrian for his help with this
driver.
This driver isn't connected to the build yet, but it will be soon.
There's no MFC planned because the driver isn't very stable yet.
