e1000: Disable autonomous PCH power gating after reset
Panther Point changed the reset value of CTRL_EXT.DPG_EN to enable
autonomous power gating. Clear it after hardware reset on Panther Point
and Nova Point controllers to prevent unexpected Tx/Rx hangs, packet
loss, or corruption.

if_vmx: fix panic during kldload
Just like vmxnet3_intr_disable_all, iflib may invoke this routine
before vmxnet3_attach_post() has run, which is before the top-level
shared data area is initialized and the device made aware of it.

fts: add fts_openat() API
Add fts_openat() as a new entry point for fts(3).
When dirfd is AT_FDCWD the behaviour is identical to fts_open().
Passing a pre-opened directory fd allows fts traversal inside
Capsicum capability mode where path-based operations are not
permitted.
Capability mode users should use fts_parent->fts_dirfd + fts_name with
openat(2) to access files.

fts: fix file descriptor leak in fts_close
fts_build() stores a dup'd file descriptor in each directory
entry's fts_dirfd. When a traversal is abandoned before
completion and fts_close() is called, the cleanup loop freed
each pending entry with free() without first closing its
fts_dirfd, leaking one descriptor per pending directory.
Close fts_dirfd before freeing each entry in the cleanup loop,
matching the handling already applied to the dummy parent entry
after the loop.
Add a regression test that descends a couple of levels, abandons
the traversal, closes, and asserts the open descriptor count is
unchanged.

SYSINIT: add SI_SUB_KENV
Since the kernel environment has its own dependencies, lurking at the end
of the SI_SUB_KMEM sequence appeared to be fragile. Provide own subsystem

Let's just adopt the C23 macros. For bonus points, I added a wrapper to

Revert "ciss: Add max physical target"
This reverts commit 45645518ea19ccb4761aee3a525aab2f323d37d4.
Although this changed looks like it should just be a harmless change to
bookkeeping, it turns out that it changes the termination condition of
the initial device scan, resulting in it never finishing. This causes
the boot to hang forever coming up. Since I don't have good access to
hardware, I'm reverting until the exact details can be sorted out.
