b9252a8889 Move ENA's hw stats updating routine to separate task
Initially, stats were being updated each time OS was requesting for
the first statistic.
To read statistics from hw, condvar was used. cv_timedwait cannot be
called when unsleepable lock is held, and this happens when FreeBSD
is requesting statistic.
Seperate task is reading statistics from NIC each 1 second.

The adapter firmware in general does not accept PDUs larger than 64k - 1
bytes in size.  Sending crypto requests larger than this size result in
hangs or incorrect output, so reject them with EFBIG.  For requests

41059135ce [ath] [ath_hal] (etc, etc) - begin the task of re-modularising the HAL.
In the deep past, when this code compiled as a binary module, ath_hal
built as a module.  This allowed custom, smaller HAL modules to be built.
This was especially beneficial for small embedded platforms where you
didn't require /everything/ just to run.

However, sometime around the HAL opening fanfare, the HAL landed here
as one big driver+HAL thing, and a lot of the (dirty) infrastructure
(ie, #ifdef AH_SUPPORT_XXX) to build specific subsets of the HAL went away.
This was retained in sys/conf/files as "ath_hal_XXX" but it wasn't
really floated up to the modules themselves.

I'm now in a position where for the reaaaaaly embedded boards (both the
really old and the last couple generation of QCA MIPS boards) having a
cut down HAL module and driver loaded at runtime is /actually/ beneficial.

This reduces the kernel size down by quite a bit.  The MIPS modules look
like this:

adrian@gertrude:~/work/freebsd/head-embedded/src % ls -l ../root/mips_ap/boot/kernel.CARAMBOLA2/ath*ko
-r-xr-xr-x  1 adrian  adrian    5076 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_dfs.ko

-r-xr-xr-x  1 adrian  adrian   23472 May 23 23:45 ../root/mips_ap/boot/kernel.CARAMBOLA2/ath_rate.ko

And the x86 versions, like this:

root@gertrude:/home/adrian # ls -l /boot/kernel/ath*ko
-r-xr-xr-x  1 root  wheel   36632 May 24 18:32 /boot/kernel/ath_dfs.ko

-r-xr-xr-x  1 root  wheel   55352 May 24 18:32 /boot/kernel/ath_rate.ko

.. so you can see, not building the whole HAL can save quite a bit.
For example, if you don't need AR9300 support, you can actually avoid
wasting half a megabyte of RAM.  On embedded routers this is quite a
big deal.

The AR9300 HAL can be later further shrunk because, hilariously,
it indeed supports AH_SUPPORT_<xxx> for optionally adding chipset support.
(I'll chase that down later as it's quite a big savings if you're only
building for a single embedded target.)

So:

* Create a very hackish way to load/unload HAL modules
* Create module metadata for each HAL subtype - ah_osdep_arXXXX.c
* Create module metadata for ath_rate and ath_dfs (bluetooth is
  currently just built as part of it)
* .. yes, this means we could actually build multiple rate control
  modules and pick one at load time, but I'd rather just glue this
  into net80211's rate control code.  Oh well, baby steps.
* Main driver is now "ath_main"
* Create an "if_ath" module that does what the ye olde one did -
  load PCI glue, main driver, HAL and all child modules.
  In this way, if you have "if_ath_load=YES" in /boot/modules.conf
  it will load everything the old way and stuff should still work.
* For module autoloading purposes, I actually /did/ fix up
  the name of the modules in if_ath_pci and if_ath_ahb.

If you want to selectively load things (eg on ye cheape ARM/MIPS platforms
where RAM is at a premium) you should:

* load ath_hal
* load the chip modules in question
* load ath_rate, ath_dfs
* load ath_main
* load if_ath_pci and/or if_ath_ahb depending upon your particular
  bus bind type - this is where probe/attach is done.

TODO:

* AR5312 module and associated pieces - yes, we have the SoC side support
  now so the wifi support would be good to "round things out";
* Just nuke AH_SUPPORT_AR5416 for now and always bloat the packet
  structures; this'll simplify other things.
* Should add a simple refcnt thing to the HAL RF/chip modules so you
  can't unload them whilst you're using them.
* Manpage updates, UPDATING if appropriate, etc.

31ce00f662 [ath] begin migration of AHB support to use the PCI style board data API for calibration data.
This brings the AHB support in line with the PCI support - now other "things"
can wrap up the calibration / board data into a firmware blob and have them
probe/attach after the system has finished booting.

Note that this change requires /all/ of the AHB using kernel configurations
to change - so until I drop those changes in, this breaks AHB.

Fear not, I'll do that soon.

6992112349 Commit the 64-bit inode project.
Extend the ino_t, dev_t, nlink_t types to 64-bit ints.  Modify
struct dirent layout to add d_off, increase the size of d_fileno
to 64-bits, increase the size of d_namlen to 16-bits, and change
the required alignment.  Increase struct statfs f_mntfromname[] and
f_mntonname[] array length MNAMELEN to 1024.

ABI breakage is mitigated by providing compatibility using versioned
symbols, ingenious use of the existing padding in structures, and
by employing other tricks.  Unfortunately, not everything can be
fixed, especially outside the base system.  For instance, third-party
APIs which pass struct stat around are broken in backward and
forward incompatible ways.

Kinfo sysctl MIBs ABI is changed in backward-compatible way, but
there is no general mechanism to handle other sysctl MIBS which
return structures where the layout has changed. It was considered
that the breakage is either in the management interfaces, where we
usually allow ABI slip, or is not important.

Struct xvnode changed layout, no compat shims are provided.

For struct xtty, dev_t tty device member was reduced to uint32_t.
It was decided that keeping ABI compat in this case is more useful
than reporting 64-bit dev_t, for the sake of pstat.

Update note: strictly follow the instructions in UPDATING.  Build
and install the new kernel with COMPAT_FREEBSD11 option enabled,
then reboot, and only then install new world.

Credits: The 64-bit inode project, also known as ino64, started life
many years ago as a project by Gleb Kurtsou (gleb).  Kirk McKusick
(mckusick) then picked up and updated the patch, and acted as a
flag-waver.  Feedback, suggestions, and discussions were carried
by Ed Maste (emaste), John Baldwin (jhb), Jilles Tjoelker (jilles),
and Rick Macklem (rmacklem).  Kris Moore (kris) performed an initial
ports investigation followed by an exp-run by Antoine Brodin (antoine).
Essential and all-embracing testing was done by Peter Holm (pho).
The heavy lifting of coordinating all these efforts and bringing the
project to completion were done by Konstantin Belousov (kib).

9b8d05b8ac Add support for Amazon Elastic Network Adapter (ENA) NIC
ENA is a networking interface designed to make good use of modern CPU
features and system architectures.

The ENA device exposes a lightweight management interface with a
minimal set of memory mapped registers and extendable command set
through an Admin Queue.

The driver supports a range of ENA devices, is link-speed independent
(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and has
a negotiated and extendable feature set.

Some ENA devices support SR-IOV. This driver is used for both the
SR-IOV Physical Function (PF) and Virtual Function (VF) devices.

ENA devices enable high speed and low overhead network traffic
processing by providing multiple Tx/Rx queue pairs (the maximum number
is advertised by the device via the Admin Queue), a dedicated MSI-X
interrupt vector per Tx/Rx queue pair, and CPU cacheline optimized
data placement.

The ENA driver supports industry standard TCP/IP offload features such
as checksum offload and TCP transmit segmentation offload (TSO).
Receive-side scaling (RSS) is supported for multi-core scaling.

The ENA driver and its corresponding devices implement health
monitoring mechanisms such as watchdog, enabling the device and driver
to recover in a manner transparent to the application, as well as
debug logs.

Some of the ENA devices support a working mode called Low-latency
Queue (LLQ), which saves several more microseconds. This feature will
be implemented for driver in future releases.

fe3ca95c9d mlx4: Use the CQ quota for SRIOV when creating completion EQs
When creating EQs to handle CQ completion events for the PF or for
VFs, we create enough EQE entries to handle completions for the max
number of CQs that can use that EQ.

When SRIOV is activated, the max number of CQs a VF (or the PF) can
obtain is its CQ quota (determined by the Hypervisor resource
tracker).  Therefore, when creating an EQ, the number of EQE entries
that the VF should request for that EQ is the CQ quota value (and not
the total number of CQs available in the firmware).

Under SRIOV, the PF, also must use its CQ quota, because the resource
tracker also controls how many CQs the PF can obtain.

Using the firmware total CQs instead of the CQ quota when creating EQs
resulted wasting MTT entries, due to allocating more EQEs than were
needed.

e6000sw family automatically reflects PHY status in each port's registers.
Therefore it is not necessary to do a full PHY polling squence, which

the SMI bus.

Care must be taken that the resulting ifmedia_active is identical to
what the PHY will compute, or gratuitous link status changes will
occur whenever the PHYs update function is called.

This patch implements above improvement. On the occasion set a pointer to

e5d27b37e3 xen/blkfront: correctly detach a disk with active users
Call disk_gone when the backend switches to the "Closing" state and blkfront
still has pending users. This allows the disk to be detached, and will call
into xbd_closing by itself when the geom layout cleanup has finished.

02fb845bbf Fix a few uses of kern_yield() in the TTM and the LinuxKPI.
kern_yield(0) effectively causes the calling thread to be rescheduled
immediately since it resets the thread's priority to the highest possible
value. This can cause livelocks when the pattern
"while (!trylock()) kern_yield(0);" is used since the thread holding the
lock may linger on the runqueue for the CPU on which the looping thread is
running.

5033c43b7a Add a driver for the Chelsio T6 crypto accelerator engine.
The ccr(4) driver supports use of the crypto accelerator engine on
Chelsio T6 NICs in "lookaside" mode via the opencrypto framework.

Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTS
cipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,
and SHA2-512-HMAC authentication algorithms.  The driver also supports
chaining one of AES-CBC, AES-CTR, or AES-XTS with an authentication
algorithm for encrypt-then-authenticate operations.

Note that this driver is still under active development and testing and
may not yet be ready for production use.  It does pass the tests in
tests/sys/opencrypto with the exception that the AES-GCM implementation
in the driver does not yet support requests with a zero byte payload.

To use this driver currently, the "uwire" configuration must be used
along with explicitly enabling support for lookaside crypto capabilities
in the cxgbe(4) driver.  These can be done by setting the following
tunables before loading the cxgbe(4) driver:

    hw.cxgbe.config_file=uwire
    hw.cxgbe.cryptocaps_allowed=-1

7118192a72 Fix broken malloc in e6000sw
Malloc should always return something when M_WAITOK flag is used,
but keep this code and change flag to M_NOWAIT as it is under a lock
(allows for possible future change). Free ifnet structure to avoid
memory leak on failure.

3e85b721d6 Remove register keyword from sys/ and ANSIfy prototypes
A long long time ago the register keyword told the compiler to store
the corresponding variable in a CPU register, but it is not relevant
for any compiler used in the FreeBSD world today.

ANSIfy related prototypes while here.
