rtwn: enable seqno offload; migrate to use ieee80211_output_seqno_assign()
This should both enable the sequence number offloading and disable
the net80211 TX lock from being acquired/released/checked.

stand: Remove Spleen 32x64 fonts from INDEX
The Spleen 32x64 fonts cause some systems such as the AMD Framework 16
to boot extremely slowly. Adding screen.font="16x32" to
/boot/loader.conf is a partial workaround, but text displayed before the
boot menu still takes ~30 seconds to render on that laptop. With this
change, the same text renders immediately.
By leaving the font files in place but removing them from the INDEX,
users who want to use them can still load them manually. Once pending
work is committed to allow normal booting with these fonts, they can be
added back to the INDEX.

LinuxKPI: devres: divorce dem_kfree from lkpi_devm_kmalloc_release
dem_kfree() is called from all over the place and should actually
do something; contrary to lkpi_devm_kmalloc_release() it can also
take a const void *. We have to __DECONST() that though as the
entire devres framework does otherwise not take a const argument.
This was discovered during the rtw89 upadte to 6.16.

This adds guard support for non-real-types like rcu locking meaning

indeed is more expressive in this case).

Take special care of DRM as there is a non-PCI device in the chain which

LinuxKPI: pci: implement [linuxkpi_]pcim_request_all_regions()
Factor out the pci_request_region() implementation into an internal
function and make pci_request_region() a simple wrapperaround it.
Likewise implement pcim_request_all_regions() as a loop calling
pci_request_region() for each entry.
In two cases which we returned an error before (bar index is valid but
bar is not (no len), and neither IO nor MEM) we now reutrn success
(nothing to do for us). Otherwise callers, especially
pcim_request_all_regions() would error out for the wrong reasons.
This seems to also match the expected behaviour of pci_request_region().

sys/netinet6: Fix SLAAC for interfaces with no /64 LL address
in6_ifadd() asserts that an interface has an existing LL address with a /64
prefix from which to extract the ifid for SLAAC address selection (even though
the comments suggest that an ifid will be generated if one does not exist). This
is adequate for most generic cases, however to support PPP links with /128 LL
addresses we must be able to fall back on another source for the ifid since we
cannot assume the /128 LL has a unique ifid in the lower 64 bits.
To do this, the static function get_ifid() in in6_ifattach.c is renamed to
non-static in6_get_ifid(), and this is used in lieu of a proper /64 LL address
to attempt to obtain a valid ifid.
