devel/py-pydbus: Switch to USE_PYTHON=pep517
Build with the PEP 517 frontend (setuptools legacy backend; the source
has no [build-system]); the package metadata becomes dist-info.

pci: Reserve bus numbers required by SR-IOV VFs
Some firmware assigns only one bus number to each PCI-PCI bridge. This
prevents later SR-IOV VF enumeration when a VF routing ID falls on a bus
number already allocated to a sibling bridge.
Reserve only the additional bus numbers required by SR-IOV PFs.
Enumerate all directly attached functions before child drivers and
bridges attach, inspect their device_t objects for SR-IOV, and grow the
PCI bus resource through the highest possible VF routing ID.
First VF Offset and VF Stride may change when NumVFs changes. Probe
every valid NumVFs value and preserve the original setting. When the
upstream hierarchy uses ARI, temporarily enable the SR-IOV ARI Hierarchy
control in the lowest-numbered PF while sizing, then restore it. Scope
active-VF detection to each conventional PCI slot; an ARI bus remains
one slot-0 hierarchy. If firmware left VFs enabled on a device, do not
modify it and reserve only its active layout.

pci_iov: Reuse downstream bridge bus window if it already covers VF bus
If the parent bridge's [secondary, subordinate] window already covers
the VF bus (e.g., programmed by BIOS or a prior PF), skip allocating
PCI_RES_BUS. This avoids a duplicate rman allocation in the multi-PF
case while still allocating when growth is actually needed.

ixl(4): Fix NVM update API
Driver provides an interface for tools operating on adapters'
Non-Volatile Memory using SIOC(G|S)DRVSPEC ioctls. It allows
tools to issue Admin Queue commands to the firmware, which
may return an error code encoded as a negative integer.
The driver passed this negative integer as the return value
of the ioctl handler. This was causing issues because the FreeBSD
kernel reserves negative error codes in system calls for special
purposes such as restarting the handler or detecting incorrect
behavior in VFS operations. Simple remapping of negative values
to positive integers caused currently available tools to misbehave
and could break the NVM update process. Introduce a new API version,
which allows new versions of tools to detect the fixed driver.
Temporarily keep the old API, but issue a warning that tools need
to be updated.
Also refactor the code to use centralized cleanup and move the
debug message from the firmware earlier to make sure it is not masked

cxgbe(4): Fix netmap rx behavior with nm_split_rss
The driver should look for active queues and one potential default-queue
in both halves of the split instead of stopping at the first valid
default-queue.

em(4): fix capability bounds needed to access checksum context.
Ensure the offp capability bounds cover entire struct with checksum fields.
This is needed for CHERI systems to avoid bounds violation trap, as
otherwise offp allowed to dereference 4 bytes of csum_flags field only
so bzero failed.
Tested on ARM Morello.

vtnet: remove M_HASHTYPE when there is only one pair of rx/tx queue
Summary:
Doing so will let the upper layer know how to deal with software hash,
with benefits like inp_flowid can be set and m_pkthdr.flowid can be set
in output path.
