Add support for the FHT_STBC_TX flag in iv_flags_ht, so it'll now obey
the per-vap ifconfig stbctx flag.
This means that we can do STBC TX on one vap and not another VAP.
(As well as STBC RX on said vap; that changes the HTCAP announcement.)
This is in preparation for exposing configuring STBC flags up to ifconfig
so STBC TX/RX can be configured at runtime.
* Set the FHT_STBC flags for TX/RX if the HT capabilitiex exist
* Clear the RX STBC HT capability flag when creating a HTCAP IE, so
we only announce it if it's configured in the FHT flags.
Tested:
* AR9331 (carambola2), AP/STA modes
Always print out the firmware panic info before restarting; don't
put it behind IWM_DEBUG.

This allows for the long function components encountered in www/firefox.

Without this change, DTrace will refuse to load a DOF section if the
function component of any of its probes exceeds DTRACE_FUNCNAMELEN (128).
Probes in C++ programs can have very long function components. Rather than
rejecting all probes if a single probe exceeds the limit, simply skip the
invalid probe and emit a warning. This ensures that valid probes are
instantiated.

When this flag is turned on, DOF and DIF validation errors are printed to
the kernel message buffer. This is useful for debugging.
Also remove the debug.dtrace.debug sysctl, which has no effect.
sysvmsg, sysvsem, and sysvshm, with the following bahavior:
inherit: allow full access to the IPC primitives. This is the same as
the current setup with allow.sysvipc is on. Jails and the base system
can see (and moduly) each other's objects, which is generally considered
a bad thing (though may be useful in some circumstances).
disable: all no access, same as the current setup with allow.sysvipc off.
new: A jail may see use the IPC objects that it has created. It also
gets its own IPC key namespace, so different jails may have their own
objects using the same key value. The parent jail (or base system) can
see the jail's IPC objects, but not its keys.

ChipCommon probing uses mapping table "chipc_devices". It calls bhnd_device_lookup,
which iterate over mapping table with end condition:
entry->desc != NULL
So if mapping table contains row with description equals to NULL, it will
stop processing of mapping. I.e. description is mandatory field and should
be not NULL.
This patch corrects mapping table for ChipCommon.

The iwm firmware has separate commands for add, modify and delete for
various things (mac, phy context, etc.) The openbsd driver has a habit
of just completely resetting the NIC each time, which is technically
mostly okay (as long as the reset doesn't actually fail!) but it means
a lot of the code is doing ADD when it should do MODIFY.
The firmware responds in kind - it just asserts.
This fixes auth attempts that occur after the NIC has been already
configured.
(I'm sure there are more instances of this!)

memory system.
RISC-V ISA has only single page table base register for both kernel
and user addresses translation. Before this commit we were using an
extra (4th) level of pagetables for switching between kernel and user
pagetables, but then realized FPGA hardware has 3-level page system
hardcoded. It is also become clear that the bitfile synthesized for
4-level system is untested/broken, so we can't use extra level for
switching.
We are now share level 1 of pagetables between kernel and user VA.
This requires to keep track of all the user pmaps created and once we
adding L1 page to kernel pmap we have to add it to all the user pmaps.
o Change the VM layout as we must have topmost bit to be 1 in the
selected page system for kernel addresses and 0 for user addresses.
o Implement pmap_kenter_device().
o Create the l3 tables for the early devmap.

Sounds strange, but both RocketCore and lowRISC do not operate

All the known implementations (Spike, QEMU, RocketCore, lowRISC) uses
default machine trap vector address and operates fine with this.

There is no need to clear all the DDR memory (we only need to clear
BSS section).
I was playing with non-default version of hardware (the bitfile
synthesized for 4-level page memory system) and clearing was helpful,
but then realized support for 4-level page system is untested/broken
in both RocketCore and lowRISC.
until after the jail is found or created. This requires unlocking the
jail for the call and re-locking it afterward, but that works because
nothing in the jail has been changed yet, and other processes won't
change the important fields as long as allprison_lock remains held.
Keep better track of name vs namelc in kern_jail_set. Name should
always be the hierarchical name (relative to the caller), and namelc
the last component.

a jail that might be seen mid-removal. It hasn't been doing the right
thing since at least the ability to resurrect dying jails, and such
resurrection also makes it unnecessary.
When ORing in a register_t to a wider integer (vm_paddr_t), it gets sign
extended, so high addresses overwrite the upper word with all 0xf. Cast to the
unsigned form (u_register_t), to avoid this problem, and get correct addresses
printed.
With this, a static environment can be compiled in via config(5). This allows,
among other things, the use of a compiled-in debug console (hw.uart.dbgport) for
kgdb.
Use own protosw structures for both address families.
Check proto in encapcheck function and use -1 as proto argument in
encap_attach_func(), both address families can have IPPROTO_IPV4
and IPPROTO_IPV6 protocols.

RFC3173 says that the IP datagram MUST be sent in the original
non-compressed form, when the total size of a compressed payload
and the IPComp header is not smaller than the size of the original
payload. In tunnel mode for small packets IPComp will send
encapsulated IP datagrams without IPComp header.
Add ip_encap handler for IPPROTO_IPV4 and IPPROTO_IPV6 to handle
these datagrams. The handler does lookup for SA related to IPComp
protocol and given from mbuf source and destination addresses as
tunnel endpoints. It decapsulates packets only when corresponding SA
is found.

It was reported via email that a Linux client couldn't do a Kerberized
NFS mount when only "sec=krb5" was specified for the exports. The Linux
client attempted a mount via krb5i and the server replied NFSERR_SERVERFAULT.
Although NFSERR_WRONGSEC isn't listed as an error for SetClientID, I
think it is the correct reply, so this patch enables that.
I do not know if this fixes the mount attempt, but adding "krb5i" to the
list of allowed security flavours does allow the mount to work.

The purpose of this file was to simply detect the UART speed before
attaching the actual ns8250 driver so that we don't have to specify the
UART speed in DTS files.
However, OpenWRT DTS files specify ns16550a as a compatible string in
their DTS files and this makes the original ns8250 driver attach to
the device. So we would have to edit the DTS files anyway and since this
is only the case for MT7621 and MT7628/MT7688 for now, it's better to
just add the clock-frequency property to those (UART is always clocked
by the same clock in both these SoCs, so that's fine) instead of having
a separate driver and still having to change the DTS files.
