Declare o<foo>_args rather than reusing the equivalent <foo>_args
structs. Avoiding the addition of a new type isn't worth the
gratutious differences.

Stop using <foo>_args structs as part of internal kernel APIs. Add
a kern_recvfrom and adjust getsockname and getpeername's equivalent
functions to take individual arguments rather than a uap pointer.
Adopt a convention from CheriBSD that a function interacting with
userspace pointers and sitting between the sys_<foo> syscall and
kern_<foo> implementation is named user_<foo>.

The socket option handler tries to ensure that the option length is no
larger than some reasonable maximum, and no smaller than sizeof(struct
dn_id). But the loaded option length is stored in an int, which is
converted to an unsigned integer for the comparison with a size_t, so
negative values are not caught and instead get passed to malloc().
Change the code to use a size_t for the buffer size.

do_config() processes a buffer of variable-length dummynet commands.
The loop which processes this buffer loads the fixed-length header
before checking whether there are any bytes left to read, so it performs
a 4-byte read past the end of the buffer before terminating.
Restructure the loop to avoid this.

When swap is turned off due to system shutdown or reboot, ignore the
check. Problem is that the check is not accurate by any means, free
page count can legitimately be low while system still able to page in
everything from the swap. Then, we turn swap off if swapping on
real file or some non-standard geom provider, and typically panic
when system appears to actually need to unavailable page.
For syscall, it is better to be safe than sorry.

HS200 and HS400 speeds can be enabled either with 1.2, or 1.8V signaling voltage.
Because of that we have four cabability flags: MMC_CAP_MMC_HS200_120,
MMC_CAP_MMC_HS200_180, MMC_CAP_MMC_HS400_120, MMC_CAP_MMC_HS400_180.
MMC logic only enables HS200/HS400 mode if both flags are set for the corresponding speed.
Fix that by being more permissive in host timing cap check.

When using cached attributes, whether or not the data cache is enabled,
fusefs must update a file's atime whenever it reads from it, so long as
it wasn't mounted with -o noatime. Update it in-kernel, and flush it to
the server on close or during the next setattr operation.
The downside is that close() will now frequently trigger a FUSE_SETATTR
upcall. But if you care about performance, you should be using
-o noatime anyway.

Over the past few months we published multiple snapshots for this
Linux derived driver and it has become fairly stable in terms of
minimal local changes needed for new updates.
The current version is based on iwlwifi-next update at
cbaa6aeedee5f92dafa5982eceea2a1f98ce4f7d with the addition of
a hand full of files replaced for FreeBSD.
Given the lack of full license texts on non-local files this is
imported under the draft policy for handling SPDX files (D29226). [1]
Do not yet hook this to the build until the remaining compat code
is all in. Along with the firmware import this will make publishing
the last bits and final testing a lot easier.

This is based on linux-firmware at f5d519563ac9d2d1f382a817aae5ec5473811ac8.
The license of the firmware matches the previous iwnfw(4) and
iwmfw(4) firmware files and you can find a copy in
sys/contrib/dev/iwlwififw/LICENCE.iwlwifi_firmware .
