f_bnxt: add kTLS (kernel TLS) TX offload

Add kTLS TX crypto offload, layered on MPC (crypto add/delete
commands submitted over its TCE channel) and TX completion coalescing
(shared tx_bd_opaque encoding).

Adds kTLS session lifecycle management, a key-context ID allocator,
HWRM key-context alloc/free with partition-mode support, and the TX
submit path: in-order packets go out on the normal iflib path with
CSUM_SND_TAG set, while out-of-order or retransmitted TLS records get
a presync command plus a replayed copy of the record built from the
driver's own replay ring. Also adds kTLS/MPC completion-time counter
sysctls and the max_ktls_entries tunable.

if_bnxt: add MPC (Mid-Path Channel) ring infrastructure

Add MPC ring support: a pair of extra, driver-private
TX/completion/notification rings the firmware uses as a side-channel
for offload commands. The only current consumer is kTLS TX crypto
command submission; RCE/CFA channel types are not yet implemented by
any consumer.

Adds MPC ring allocation/teardown, HWRM ring alloc/free, a private
interrupt path for the MPC NQ ring, and the TX submit/completion
path. The RoCE-only IRQ table builder is split into a generic,
exported bnxt_populate_irq(softc, irq_count) that both MPC and RoCE
use, plus an incremental bnxt_populate_irq_roce() that grows the
table on top of whatever is already there, so IRQ rids stay
consistent regardless of attach order.

This patch does not link standalone: bnxt_mpc_cmp() calls into
kTLS's completion handler, added by a later patch.

vm_swapout: Restore handling of RLIMIT_RSS

In commit 13a1129d700c, I removed the mechanism by which the pagedaemon
signals the swapout thread when page reclamation is unable to keep up
with demand. This is because the swapout thread's main action in this
case is to swap out sleeping processes, but we removed this support.

However, it had the secondary effect of causing the swapout thread to
enforce RLIMIT_RSS when racct is not enabled. Without it, if
racct_enabled is false, nothing ever kicks the swapout thread.

Restore the old behaviour of trying to enforce RLIMIT_RSS when the page
daemon is unable to keep up with demand. I'm not at all convinced this
is a good way to implement the limit, but the change wasn't intentional,
so let's restore it for now.

ixv: Add Hyper-V virtual function support

Hyper-V does not expose the normal Intel PF/VF mailbox.

Import the Hyper-V operation overrides from DPDK and complete its reset
callback with the configuration-space mechanism submitted by Microsoft.
Route ixv operations through the operation table, use mailbox API 1.0,
and limit this environment to one queue pair.

Claim the 82599, X540, X550, X550EM-X, and X550EM-A Hyper-V device IDs
listed by DPDK. Select the same path for the E610 Hyper-V subdevice
identity defined there.

For E610/Linkville, read the emulated VFLINKS-format status from PCI
configuration space at offset 0x209. Older families retain the MMIO
VFLINKS path.

Treat receive-mode changes as host-owned no-ops and do not retry VLAN
operations that Hyper-V permanently rejects. Limit the Hyper-V 82599
MTU to 1504 because its VF does not implement the X540 RLPML field.

Use mailbox reset indications only to refresh cached Hyper-V link state.
Hyper-V does not provide the mailbox handshake required to treat that
indication as a request for an iflib reinitialization.

Tested on 82599 and E610 (with a followup commit) with Windows Server
2025 Hyper-V.

Stop shared setup from accessing PF-only controls. Require MSI-X and

Advertise only VF capabilities, run adaptive moderation without the
PF receive-buffer guard, enable SRRCTL.DROP_EN, and provide a VF-safe

igb: Add SR-IOV PF support for 82576 and I350

one hardware queue per pool. Implement VF mailbox handling, MAC and
VLAN assignment, multicast filtering, promiscuity policy,
anti-spoofing, malicious-driver recovery, reset replay, and queue
lifecycle management.

The basic SR-IOV and VMDq PF implementation follows DPDK Intel e1000
code, including PF pool selection, one queue per pool, mailbox
dispatch, and VF enablement. Intel FreeBSD igb-2.5.31 supplies the
older driver baseline. Linux igb and the Intel SDMs clear up lifecycle,
isolation, reset, and family-specific details absent from DPDK.

Enabling IOV requires the PF to attach with one TX and RX queue.
Systems whose defaults select RSS queues must set the documented iflib
queue override tunables before attach.

Only 82576 and I350 support SR-IOV in silicon. The series has been
extensively tested on I350, including thowing boundaries at the PCI BAR
that shipping drivers will never. Still, think carefully before
reaching for this in critical environments.

LinuxKPI: page pool updates and add to the build

Split implementation out from the header files.

This "page pool" is the very minimalistic version we need in order to
support packets on mt76.
We allocate the page pool in order to have the meta data available of
which we only make limited use.
This implementation does no pooling, it does no page fragments for now,
it always hands out a full page and frees it upon return.

It is written in a way that it can be in the tree before the 'struct page'
work it depends on has landed in order to reduce friction for people who
want to try mt7921 (or others later) upfront. We use the same #ifdef
as in the struct page work for that reason so one knob will turn everything
on or off.

Once the struct page work has landed and settled we can start filling this
with more complexity.

In the unlikely event that in the mean time any other consumer would start
showing up they will have to be aware that the current code as-is
essentially is a NOP without the 'struct page' work. A WARN_ONCE() will
notify them.

aq(4): add Atlantic 2 (AQC113) device support

Add support for the Marvell Atlantic 2 (AQC113/114/115/116) controllers,
a new chip generation that is not register-compatible with the Atlantic 1
parts aq(4) supports today. Adapted from the OpenBSD/NetBSD if_aq driver.

Register and device definitions (aq2_hw.h): the firmware handshake
(MIF_BOOT / MCP_HOST_REQ_INT / MIF_HOST_FINISHED), the 0x12000/0x13000
firmware interface windows, and the action-resolver table (ART) that
replaces Atlantic 1's discrete RX filters, plus the Atlantic 2 PCI device
ids and the aq_is_atlantic2() helper. Reserve a chip-feature bit
(AQ_HW_CHIP_ATLANTIC2) and add the aq_hw fields the firmware fills at boot
(ART base index, statistics interface version A0/B0). The per-VLAN-filter
resolver-tag field comes from the Linux driver; the BSD sources never
write it.

Firmware operations (aq_fwa2.c): Atlantic 2 talks to the management CPU
through the 0x12000/0x13000 register windows plus the boot handshake,
rather than Atlantic 1's mailbox in shared RAM. Implement that as a third
aq_firmware_ops vtable (reset, set_mode, get_mode, get_mac_addr,
get_stats); aq_fwa2_reboot() boots the firmware, selects the A2 ops, and
reads the version and ART base index, failing fast on the
crash-init / boot-failed bits. fwa2_set_mode advertises full duplex only
(the media model exposes no half-duplex types) and writes and acks the
link options before raising ACTIVE mode, so a forced media change does not
begin negotiation with a stale rate mask. enum aq_fw_link_speed gains
aq_fw_10M, which Atlantic 2 supports and Atlantic 1 does not.

Probe and attach: list the device ids with their media types and link
speeds (all copper; AQC113* up to 10G, AQC116C to 1G), populate
hw->device_id, and tag the generation with AQ_HW_CHIP_ATLANTIC2 so
IS_CHIP_FEATURE() recognises it uniformly. Branch firmware bring-up and
reset on the generation: aq_hw_init_ucp() and aq_hw_reset() reboot the MCP
instead of the Atlantic 1 RBL/FLB reset -- without a real datapath reset
every stop/init cycle reprograms the rings on a live, desynced RX DMA
engine and the receive path stays dead. aq_hw_init() programs the
Atlantic 2 launch-time clock ratio in place of the Atlantic 1
MRRS / TX-DMA request-limit clamp. Add an AQ_LINK_10M capability bit
(Atlantic 2 links at 10M, Atlantic 1 cannot), offer 10baseT media, and map
IFM_10_T to aq_fw_10M.

With every supported media type now present, replace the per-speed switch
statements in aq_media.c with a single {link bit, fw rate, IFM_* subtype,
Mbit/s} table -- one source of truth for the supported link speeds.

With this an Atlantic 2 card probes, brings up its firmware, reads its
MAC, and negotiates link; the RX action-resolver datapath comes next.

hidwacom: Add Wacom ExpressKey Remote driver

The Wacom ExpressKey Remote (ACK-411050) is a wireless button pad
with 18 programmable buttons and a touch ring, used as a companion
device with Wacom tablets.

It communicates via a USB wireless receiver (0x056a:0x0331) using a
vendor-specific HID report (ID 0x11).

This driver exposes the device via evdev:
- 18 buttons: BTN_0–BTN_Z, BTN_BASE, BTN_BASE2
- Touch ring position via ABS_WHEEL (0–71; reports 0 on release)
- Pad activity marker via ABS_MISC (set to 15/PAD_DEVICE_ID when
any input is active, 0 when idle that matches Linux wacom driver
convention)
- Remote serial number via MSC_SERIAL (for userland per-remote
identification)

Battery level, charging state, and touch ring mode (3 LEDs, values 0–2)
are exposed as per-device sysctls (dev.hidwacom.0.battery, .charging,
.ring_mode) rather than overloading evdev misc codes. The ring mode
sysctl is preserved across device idle periods.

Protocol was decoded from USB traffic analysis and cross-referenced
against the Linux wacom_remote_irq() implementation in
drivers/hid/wacom_wac.c.
