Only HMAC-SHA256 is added as it is the only SHA-2 variant supported by
cryptodev. It is not possible to register hardware support for other

1e964f8a52 Truncate HMAC output only if requested by the client
The output of HMAC was previously truncated to 12 bytes. This was only
correct in case of one particular crypto client - the new version of IPSEC.
Fix by taking into account the cri_mlen field in cryptoini session request
filled in by the client.

22c7a03178 Split CESA memory resource into TDMA and CESA regs
TDMA and CESA registers are placed in different ranges of memory. Split
memory resource in DTS to reflect that. This change is needed to support
multiple CESA nodes as otherwise the ranges of different nodes would
overlap.

In consequence, CESA_WRITE and CESA_READ macros have been split depending
on which range of registers is accessed. Offsets for CESA registers have
been modified as the base address has changed.

5188e3cca6 Map CESA SRAM memory in driver attach for Armada38x
On other platforms with CESA accelerator the SRAM memory is mapped in
early init before driver is attached. This method only works correctly
with mappings no smaller than L1 section size (1MB). There may be more
SRAM blocks and they may have smaller sizes than 1MB as is the case
for Armada38x. Instead, map SRAM memory with bus_space_map() in CESA
driver attach. Note that we can no longer assume that VA == PA for the
SRAM.

Otherwise we transmit the first neighbour solicitation in the context of the
caller of nd6_dad_start(), which can easily result in lock recursion. When
DAD is to be started after some delay, we send the first NS from the DAD

c21b47d8c9 xen-netfront: fix two hotplug related issues
This patch fixes two issues seen on hot-unplug. The first one is a panic
caused by calling ether_ifdetach after freeing the internal netfront queue
structures. ether_ifdetach will call xn_qflush, and this needs to be done
before freeing the queues. This prevents the following panic:

This is caused by marking the driver as active before it's fully
initialized, and thus calling xn_txq_mq_start with num_queues set to 0.

da695b059d xen-netfront: switch to using an interrupt handler

is basically what is already done for an interrupt handler, or else we risk
loosing interrupts. This switches netfront to the same interrupt handling
that was done before multiqueue support was added.

2568ee6747 xen-netfront: always keep the Rx ring full of requests
This is based on Linux commit 1f3c2eba1e2d866ef99bb9b10ade4096e3d7607c from
David Vrabel:

A full Rx ring only requires 1 MiB of memory.  This is not enough memory
that it is useful to dynamically scale the number of Rx requests in the ring
based on traffic rates, because:

a) Even the full 1 MiB is a tiny fraction of a typically modern Linux
   VM (for example, the AWS micro instance still has 1 GiB of memory).

b) Netfront would have used up to 1 MiB already even with moderate
   data rates (there was no adjustment of target based on memory
   pressure).

c) Small VMs are going to typically have one VCPU and hence only one
   queue.

Keeping the ring full of Rx requests handles bursty traffic better than
trying to converge on an optimal number of requests to keep filled.

bcf5fc498a [ath] commit initial bluetooth coexistence support for the MCI NICs.
This is the initial framework to call into the MCI HAL routines and drive
the basic state engine.

The MCI bluetooth coex model uses a command channel between wlan and
bluetooth, rather than a 2-wire or 3-wire signaling protocol to control things.
This means the wlan and bluetooth chip exchange a lot more information and
signaling, even at the per-packet level.  The NICs in question can share
the input LNA and output PA on the die, so they absolutely can't stomp
on each other in a silly fashion.  It also allows for the bluetooth side
to signal when profiles come and go, so the driver can take appropriate
control.  There's also the possibility of dynamic bluetooth/wlan duty cycle
control which I haven't yet really played with.

It configures things up with a static "wlan wins everything" coexistence,
configures up the available 2GHz channel map for bluetooth, sets a static
duty cycle for bluetooth/wifi traffic priority and drives the basics needed to
keep the MCI HAL code happy.

It doesn't do any actual coexistence except to default to "wlan wins everything",
which at least demonstrates that things do indeed work.  Bluetooth inquiry frames
still trump wifi (including beacons), so that demonstrates things really do
indeed seem to work.

Tested:

* AR9462 (WB222), STA mode + bt
* QCA9565 (WB335), STA mode + bt

TODO:

* .. the rest of coexistence.  yes, bluetooth, not people.  That stuff's hard.
* It doesn't do the initial BT side calibration, which requires a WLAN chip
  reset.  I'll fix up the reset path a bit more first before I enable that.
* The 1-ant and 2-ant configuration bits aren't being set correctly in
  if_ath_btcoex.c - I'll dig into that and fix it in a subsequent commit.
* It's not enabled by default for WB222/WB225 even though I believe it now
  can be - I'll chase that up in a subsequent commit.

a7c5163b5f When we are in panic, always go the asynchronous path in g_mirror_destroy(),
otherwise the system will hang.

This is a temporarily least intrusive crutch to get certain panicing systems
dumping. The proper fix should question is g_mirror_destroy() should be called
on a panicing system at all.

9de9fa32c9 thr_*(2): Add xrefs to what libthr implements using each syscall.
Add text to thr_exit(2) and thr_new(2) discouraging their use in
applications since calling these in a process with libthr loaded will
confuse libthr and is likely to cause hangs or crashes.

The thr_kill2(2) call is not used by libthr and may be useful in special
applications.

The other calls can be used in applications but it should not be necessary.
