vmm: Emulate CPUID leaf 1Fh for guests
On an Intel N150 host a guest started with sockets=1, cores=4,
threads=1 reports "1 package(s) x 2 core(s) x 2 hardware threads"
instead of four cores with one thread each, while the host itself
detects its topology correctly.
A FreeBSD guest picks the topology leaf in topo_probe_intel_0xb(),
sys/x86/x86/mp_x86.c, and since 6badb512a94d it prefers leaf 1Fh over
leaf 0Bh whenever cpu_high is 1Fh or higher. bhyve passes leaf 0
through unmodified, so the guest sees the maximum basic leaf of the
host, which is 1Fh or above on Alder Lake and newer, and takes that
path. x86_emulate_cpuid(), sys/amd64/vmm/x86.c, derives the topology
from vm_get_topology() for leaves 1, 4 and 0Bh, but has no case for
1Fh, so the request ends up in default_leaf and the host values are
returned verbatim. The guest therefore enumerates the topology of the
host: with an SMT shift of 1 in the host's leaf 1Fh and four vCPUs this
gives core_id_shift = 1 and pkg_id_shift = 2, which is exactly the
reported 2 cores x 2 threads. Hosts whose maximum basic leaf is below

mkimg: Const correctness for C23
On some platforms, e.g. Linux Clang 22.1.8 / glibc 2.43, strchr()
now implements the C23 behaviour where passing a const pointer to
strchr() also returns a const pointer. This breaks mkimg during
the bootstrap build, since it assumes the return value is always
a mutable pointer.
Make the existing 'sep' pointer const to fix the first case, and
for the second, introduce a new non-const pointer for strchr,
since we do modify the result in that case.

igc: Report corrected internal ECC errors
I225 and I226 do not interrupt for corrected internal ECC errors.
Instead, the DMA packet buffer and PCIe memories expose sticky status
bits in PBECCSTS and PCIEECCSTS.
Sample these bits with the regular hardware statistics update, preserve
the PBECCSTS ECC enable state while clearing its RW1C indication, and
expose separate counters for the DMA packet buffer, PCIe transmit-data
memory, and PCIe retry buffer.
These counters represent observed indications rather than an exact error
count because multiple corrections between samples collapse into one
sticky status bit.
Hardware validation used an I225-IT (rev 3) and a debug kernel that
wrote only the documented self-clearing injection bits. Each test
armed the injector, exercised the owning RAM with traffic, and compared
the corresponding counter before and after.

igc: Recover from fatal internal memory errors
I225 and I226 report uncorrectable internal memory errors through
ICR.FER and identify the affected region in PEIND. Depending on the
region, hardware stops transmit or all PCIe and DMA traffic until the
port is reset and reinitialized.
Enable the fatal error interrupt and capture its read clear status in
the interrupt filter. Mask the cause while an iflib reset is pending,
report the affected memory regions, and expose per region indication
counters.
PCIe region parity failures require a different recovery order from a
normal reset: assert DEV_RST, wait at least 3 ms, disable PCIe master
requests, clear PCIEERRSTS, and then reinitialize the port. Follow that
sequence before entering the normal reset path and clear the remaining
LAN status afterward.
The I225/I226 PBECCSTS layout is unrelated to the PCH layout previously

ixgbe: Defer E610 thermal shutdown to iflib
The E610 firmware event handler invoked ixgbe_if_stop() directly from
IFDI_UPDATE_ADMIN_STATUS(). This reset the device without the iflib
queue lifecycle and left the interface marked running after its hardware
was stopped.
Request an iflib reset instead. Fail the automatic initialization once
so the reset transaction stops the interface and publishes that state.
A later operator-requested initialization remains possible, matching the
previous recovery policy without bypassing iflib.

ixgbe: Defer firmware recovery transitions to iflib
The firmware-mode callout invoked ixgbe_if_stop() directly. This
performed a full device reset without the iflib context lock or the
iflib queue lifecycle. It could also poll the E610 firmware command
interface from callout context while identification was active.
Request an iflib reset from the callout instead. Reject initialization
while firmware recovery remains active. This leaves the interface
stopped and lets iflib publish that state. Request initialization when
firmware exits recovery so an administratively-up interface can recover
without operator intervention.

ixgbe: Defer ECC recovery to iflib
The link interrupt filter performed a full hardware reset in interrupt
context. This bypassed iflib stop and initialization, including queue
quiescence and restoration of temporary LED state.
Record the ECC event in the administrative request mask and ask iflib
to perform the reset from its taskqueue. Keep the ECC cause masked
until reset so the intermediate admin pass cannot re-enable a sticky
condition. Handle ECC independently of Flow Director and in legacy
interrupt mode.
Remove the redundant EICR write; the filter has already cleared the
reported causes. Also remove the accompanying complement-mask update
of mac.flags. It set every flag except DOUBLE_RESET_REQUIRED and had
no place in ECC recovery.
