SCTP will only do IPv4 UDP checksum calculation as defined by the host
policy. When tunneling SCTP always calculates the inner checksum already
so not doing the outer UDP can save cycles.
While here virtualize the variable.

The flash commands and responses are little-endian and have to be
byte swapped on big-endian systems. However the raw read of data
need not be swapped.
Make the cfi_read and cfi_write do the swapping, and provide a
cfi_read_raw which does not byte swap for reading data from
flash.
loaded and unloaded, also have sdt.ko register callbacks with kern_sdt.c
that will be called when a newly loaded KLD module adds more probes or
a module with probes is unloaded.
This fixes two issues: first, if a module with SDT probes was loaded after
sdt.ko was loaded, those new probes would not be available in DTrace.
Second, if a module with SDT probes was unloaded while sdt.ko was loaded,
the kernel would panic the next time DTrace had cause to try and do
anything with the no-longer-existent probes.
This makes it possible to create SDT probes in KLD modules, although there
are still two caveats: first, any SDT probes in a KLD module must be part
of a DTrace provider that is defined in that module. At present DTrace
only destroys probes when the provider is destroyed, so you can still
panic the system if a KLD module creates new probes in a provider from a
different module(including the kernel) and then unload the the first module.
Second, the system will panic if you unload a module containing SDT probes
while there is an active D script that has enabled those probes.

Move XLP PCI UART device to sys/mips/nlm/dev/ directory. Other
drivers for the XLP SoC devices will be added here as well.
Update uart_cpu_xlp.c and uart_pci_xlp.c use macros for uart port,
speed and IO frequency.

On XLP evaluation platform, the board information is stored
in an I2C eeprom and the network block configuration is available
from a CPLD connected to the GBU (NOR flash bus). Add support
for both of these.
Support for the Security and RSA blocks on XLP SoC. Even though
the XLP supports many more algorithms, only the ones supported
in OCF have been added.

within the BAW.
This regression was introduced in ane earlier commit by me to fix the
BAW seqno allocation-but-not-insertion-into-BAW race. Since it was only
ever using the to-be allocated sequence number, any frame retries
with the first frame in the BAW still in the software queue would
have constantly failed, as ni_txseqs[tid] would always be outside
the BAW.

pam_exec(8) now accepts a new option "return_prog_exit_status". When
set, the program exit status is used as the pam_exec return code. It
allows the program to tell why the step failed (eg. user unknown).
However, if it exits with a code not allowed by the calling PAM service
module function (see $PAM_SM_FUNC below), a warning is logged and
PAM_SERVICE_ERR is returned.
The following changes are related to this new feature but they apply no
matter if the "return_prog_exit_status" option is set or not.
The environment passed to the program is extended:
o $PAM_SM_FUNC contains the name of the PAM service module function
(eg. pam_sm_authenticate).
o All valid PAM return codes' numerical values are available
through variables named after the return code name. For instance,
$PAM_SUCCESS, $PAM_USER_UNKNOWN or $PAM_PERM_DENIED.
pam_exec return code better reflects what went on:
o If the program exits with !0, the return code is now
PAM_PERM_DENIED, not PAM_SYSTEM_ERR.
o If the program fails because of a signal (WIFSIGNALED) or doesn't
terminate normally (!WIFEXITED), the return code is now
PAM_SERVICE_ERR, not PAM_SYSTEM_ERR.
o If a syscall in pam_exec fails, the return code remains
PAM_SYSTEM_ERR.
waitpid(2) is called in a loop. If it returns because of EINTR, do it
again. Before, it would return PAM_SYSTEM_ERR without waiting for the
child to exit.
Several log messages now include the PAM service module function name.
The man page is updated accordingly.

I see traffic stalls.
It turns out that the bug isn't because the first and last frame in the
BAW is in the software queue. It is more likely that it's because
the first frame in the BAW is still in the software queue and thus there's
no more room to allocate and do subsequent TX.
