This change does modify devsw dv_print() to return the int value,
enabling walkers to interrupt the walk on non zero value from dv_print().
This will allow the pager_print actually to stop displaying data on
user input, and additionally pager is used in various *dev_print callbacks,
where it was missing.
For test, lsdev [-v] command should display data by screenfuls and should
stop when the key 'q' is pressed on pager prompt.

when one is not administratively assigned. The driver should check for
this case and generate a random address, similar to how the linux igbvf

more buffers in case we are temporarily out of mbufs. Else

machine/armreg.h requires access to the __ARM_ARCH macro, which is not
always properly defined (especially by gcc 4.2.1). We should include
sys/cdefs.h in order to get the definitions in machine/acle-compat.h,
which would properly define the __ARM_ARCH macro in these cases.
So, in cases where machine/armreg.h is included without _SYS_CDEFS_H_
being defined - generate an #error.

NOTE: some multi-vap configurations (e.g., STA+IBSS) are not stable;
that will be fixed later.
Tested with:

- RTL8188CE, IBSS mode;
- RTL8188CUS, IBSS mode;
- RTL8188EU, IBSS mode.
Relnotes: yes
Also - allow driver specific bits to be added, rather than just net80211.
This still isn't as useful as it should be by default; it needs to
be a standalone struct/instance so it can be done before net80211
registration occurs, and it can log per-device items.
But, it's getting there.
rtwn_usb: drain USB transfers during device shutdown; this fixes possible
panic with 'options IEEE80211_SUPPORT_SUPERG' during device detach.
Tested with RTL8188CE, STA mode.
Do not try to clear stale Tx descriptor entries when there are some
running vaps; just free node references - rtwn_pci_tx_done() will free
mbufs without creating holes in the Tx descriptor space.
Also, reset only 2 first entries in the beacon ring - other will not be
used anyway.
Tested with RTL8188CE, STA + STA mode.
- Correctly refresh Rx filter when AP (IBSS) vap is created after STA vap.
- Block any RCR updates during TSF correction (IBSS mode).
- Set CBSSID* bits during vap creation, not when it was started / stopped.
- Cache current state to prevent unnecessary register reads.
Tested with RTL8188CE, STA + AP mode.
* extend the keycache flag word to be 32 bits, not 16 bits
* add new key flags for transmit:
+ IEEE80211_KEY_NOIV: Don't insert IV in the payload when transmitting data frames;
+ IEEE80211_KEY_NOIVMGT: Don't insert IV in the payload when transmitting MIC frames;
+ IEEE80211_KEY_NOMIC: Don't insert MIC in the payload when transmitting data frames;
+ IEEE80211_KEY_NOMICMGT: don't insert MIC in the payload when transmitting management
frames.
* teach ieee80211_crypto_demic() about hardware decrypted frames:
+ if frames are hardware decrypted and the frame has failed MIC, treat it as a
michael failure.
+ if frames are hardware decrypted and the frame has stripped MIC, we can't check the
MIC in the payload - we don't have anything to compare it against.
This is only part of the work required to successfully transmit/receive
hardware crypto frames such as the qualcomm atheros 11ac offload chips.
There will be further work in the transmit and receive path before this
can be done by default.

adapter to work around bugs in TSO handling at this speed.
em_init_locked is called during first boot of the adapter and will
see that link_speed is unitialized, effectively turning off tso for
all cards at all speeds, which I believe was *not* the intent.
Move the handling of TSO deactivation to the link handler where we can
more effectively make the decision about what to do. In addition,
completely purge the TSO capabilities instead of disabling just CSUM_TSO.
Thanks to jhb for explanation of the hw capabilites api.
Thanks to royger and cognet for testing the 100Mbit failure case to

Bay Trail has three banks of GPIOs exposed to userland as /dev/gpiocN,
where N is 1, 2, and 3. Pins in each bank are pre-named to match names
on boards schematics: GPIO_S0_SCnn, GPIO_S0_NCnn, and GPIO_S5_nn.
Controller supports edge-triggered and level-triggered interrupts but
current version of the driver does not have interrupts support
Requests which cannot be satisfied by allocators at boot time often
have unrealizable parameters. Waiting for the pagedaemon' start would
hang the boot if done in the thread0 context and just never succeed if
executed from another thread. In fact, for very early stages, sleep
attempt panics with obscure diagnostic about the scheduler state, and
explicit panic in vm_wait() makes the investigation much shorter by
cut off the examination of the thread and scheduler.
Theoretically, some subsystem might grab a resource to exhaustion, and
free it later in the boot process. If this unlikely scenario does
appear for real, the way to diagnose the trouble can be revisited.
