Pass current thread credentials instead of NOCRED.
Only allow unmapped buffers for filesystem which proclaimed the support.
For all filesystems which currently use buffer pager (UFS, msdosfs and
cd9660), the changes are effectively nop.

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
driver does.

The firmware/hardware does not generate additional completion
events unless we post new buffers. Use a timer to try to post
more buffers in case we are temporarily out of mbufs. Else
the receive schedule completely stops.

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, STA + AP mode;
- 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.
[AArch64] PR28877: Don't assume we're running after legalization when
creating vcvtfp2fxs
Summary:
The DAG combine transformation that was generating the
aarch64_neon_vcvtfp2fxs node was assuming that all inputs where legal
and wasn't accounting that the input could be a v4f64 if we're trying
to do the transformation before legalization. We now bail out in this
case.
All illegal types besides v4f64 were already rejected.

* 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.
