Add the nvmeX device to the XPT_PATH_INQ nvme specific
information. while one could figure this out by looking up the
domain🚌slot:function, it's a lot easier to have the SIM set it
directly since the sim knows this.
This largely reuses the TLS TOE support added in r330884. However,
this uses the KTLS framework in upstream OpenSSL rather than requiring
Chelsio-specific patches to OpenSSL. As with the existing TLS TOE
support, use of RX offload requires setting the tls_rx_ports sysctl.

- Add a new TCP_RXTLS_ENABLE socket option to set the encryption and
authentication algorithms and keys as well as the initial sequence
number.
- When reading from a socket using KTLS receive, applications must use
recvmsg(). Each successful call to recvmsg() will return a single
TLS record. A new TCP control message, TLS_GET_RECORD, will contain
the TLS record header of the decrypted record. The regular message
buffer passed to recvmsg() will receive the decrypted payload. This
is similar to the interface used by Linux's KTLS RX except that
Linux does not return the full TLS header in the control message.
- Add plumbing to the TOE KTLS interface to request either transmit
or receive KTLS sessions.
- When a socket is using receive KTLS, redirect reads from
soreceive_stream() into soreceive_generic().
- Note that this interface is currently only defined for TLS 1.1 and
1.2, though I believe we will be able to reuse the same interface
and structures for 1.3.
Instead, copy the strings into a temporary buffer on the stack and
run strcmp on the copies.

Use DRIVER_MODULE_ORDERED(SI_ORDER_ANY) so that ig4's ACPI attachment
happens after iicbus and acpi_iicbus drivers are registered.
I have seen a problem where iicbus attached under ig4 instead of
acpi_iicbus when ig4.ko was loaded with kldload. I believe that that
happened because ig4 driver was a first driver to register, it attached
and created an iicbus child. Then iicbus driver was registered and,
since it was the only driver that could attach to the iicbus child
device, it did exactly that. After that acpi_iicbus driver was
registered. It would be able to attach to the iicbus device, but it was
already attached, so nothing happened.

In r360131, acpi_ec probe was changed to not clobber an error status prior to
several error cases that did not explicitly set the error variable before
goto'ing the exit path. However, I did not notice that the error variable was
not set to success in the success path. That caused all successful probes to
fail, which is obviously undesirable.

All of the 'goto out;' cases in this probe routine without explicit
initialization of 'ret' indicate error cases and were clearly intended
to use the initial definition of 'ret' with ENXIO. However, 'ret' was
accidentally squashed by reuse for a subroutine call near the beginning
of probe.
Use a different variable for the subroutine status to preserve ENXIO ret
for the 'goto out's as a minimal solution to the panic reported at attach
for now.

A later change, currently being iterated on in D24459, will in-fact change
the lock type to an sx so that TTY drivers can sleep on it if they need to.
Committing this ahead of time to make the review in question a little more
palatable.
tty_lock_assert() is unfortunately still needed for now in two places to
make sure that the tty lock has not been recursed upon, for those scenarios
where it's supplied by the TTY driver and possibly a mutex that is allowed
to recurse.

KTLS uses the flowid to distribute software encryption tasks among its
pool of worker threads. Without this change, all software KTLS
requests for TOE sockets ended up on the first worker thread.
Note that the flowid for TOE sockets created via connect() is not a
hash of the 4-tuple, but is instead the id of the TOE pcb (tid). The
flowid of TOE sockets created from TOE listen sockets do use the
4-tuple RSS hash as the flowid since the firmware provides the hash in
the message containing the original SYN.
