Material's defaults (Roboto, bluish slate dark mode) looked dull next
to the Chirpy-based kernelkit.org blog. Match its typography and colors
via extra.css, no engine change:
- Lato headings + Source Sans 3 body + system monospace for code
- Dark mode: neutral near-black background, soft-gray text, darker code
blocks, Chirpy blue links (replacing Material's high-contrast slate)
- Light mode: warmer body text, blue links, tinted sidebars
- Keep the orange brand on the masthead; links use Chirpy blue
Set theme.font: false so Material no longer also fetches Roboto.

Extend the existing 'show <running|startup|factory>-config' family with an
optional 'path /XPATH' argument that maps straight to the underlying 'copy
-x' flag, and add 'show operational [path /XPATH]' for symmetry with the
configuration datastores.
admin@example:/> show running-config path /ietf-interfaces:interfaces
admin@example:/> show operational path /ietf-system:system-state
Also, improve error feedback from the copy command slightly.
Before:
admin@example:~$ copy running -x /foo
Error: (null) (5)
Error: failed retrieving running-config data
After:
admin@example:~$ copy running -x /foo
Error: Couldn't parse path "/foo": Prefix "foo" not defined. (5)
Error: failed retrieving running-config data

The Ethernet packet/RMON counters at the bottom of 'show interface
<name>' were appended with a wider label column than the operational
data above them, breaking visual alignment. Group them under an
"Ethernet Statistics" section heading (Decore.title), same convention
as 'Available Networks' in the wifi scan view.
Narrow the operational-data label column from 20 to 19 chars so the
title bar exactly matches the heading text — a tighter and more
deliberately aligned look. All labels in pr_iface fit within 19
chars except 'lacp system priority' (20); rename it to 'lacp sys
priority' for consistency with the other 'lacp ...' labels (lacp
aggregate id, lacp partner mac, ...) so the new field width works
universally.
Refresh CLI snapshots and doc samples to match.

Fix#1506: restore the VLAN interface documentation that was lost when
networking.md was split into per-topic pages. Content adapted from the
v25.11.0 networking.md VLAN section, plus a new "Stacked (Q-in-Q)"
section showing `eth0.10.20`-style nesting and the layered `show
interface` rendering of the parent chain.
Update the interface-type table in networking.md to point at the new
vlan.md instead of the dangling ethernet.md#vlan-interfaces anchor.
ChangeLog: document the user-facing changes on this branch (YANG model
upgrade, layered show interface output, auto-negotation typo fix) and
the new VLAN documentation.

Import ieee802-ethernet-interface@2025-09-10.yang, from IEEE 802.3.2-2025,
and companion ieee802-ethernet-phy-type.yang, replacing the 2019 revision.
Operational interface speed moves to ietf-interfaces:speed, RFC 8343,
eth:speed is now obsolete. Bump infix-interfaces.yang revision to track
the upgrade.
The CLI 'show interface' command renders interfaces as bottom-up layered
protocol rows. Ethernet interfaces a new IEEE link-mode row (1000baseT,
10GbaseLR, ...) is added with 'duplex: full|half' in the DATA column.
Without link the ethernet row is the first row. Tunnels and wifi follow
the same layering: gre/vxlan rows carry remote:/vni: tokens with optional
ethernet sub-row for the L2-bearing variants; wifi rows carry 'station' or
'access-point' ssid:, signal:, stations: tokens.

yanger populates phy-type and pmd-type from a static ETHTOOL link-mode
identity table keyed on (port, speed, duplex). Both leaves are populated
for unambiguous media (copper, DAC, copper-T); for generic fiber where
the (port, speed, duplex) tuple can map to multiple PMDs (SR vs LR vs
ER, etc.) only the phy-type family identity is emitted — guessing the
PMD would be misleading. cli_pretty prefers pmd-type (specific) and
falls back to phy-type (family) for display.
yanger also emits ietf-interfaces:speed and fixes a long-standing
'auto-negotation' typo (yanger had never matched ethtool's correctly-
spelled JSON field, so operational auto-negotiation always read
'unknown').
Filling the WG's gap on fixed-speed config
------------------------------------------
IEEE Std 802.3.2-2025 obsoleted the eth:speed leaf without providing a
config-true replacement; the standards-correct way to express what
older Infix configurations called 'fixed speed' is to restrict the set
of PMDs auto-negotiation may advertise. Augment auto-negotiation with
two leaf-lists:
auto-negotiation/advertised-pmd-types config-true, leaf-list of pmd-type
ethernet/supported-pmd-types config-false, leaf-list of pmd-type
Pinning a port to a single mode is now expressed as a single-entry
advertised-pmd-types list. The kernel-supported set is exposed as
operational state for diagnosis — SFP/SFP+ cages report the inserted
module's capabilities, narrowing the list to a single PMD when the
optic only supports one mode (as suggested by @wkz in PR review).
When the supported list collapses to a single entry, yanger uses it
to refine the operational pmd-type leaf — more accurate than the
(port, speed, duplex) lookup for fiber.
confd C apply path (src/confd/src/ieee802-ethernet-interface.c)
translates each advertised pmd-type identity to the corresponding
ETHTOOL_LINK_MODE_*_BIT_*, ORs them into a mask, and emits
'ethtool --change <if> autoneg on advertise 0x<mask>'. An empty
list keeps the historical default of advertising every supported
mode. The (legacy) 'auto-negotiation/enable = false' + speed/duplex
branch is removed — it has no model representation any more.
cli_pretty's detail view gains 'advertised' and 'supported' rows
listing the PMDs in each set. A new _pr_label_list() helper unifies
multi-row rendering across these new rows and the pre-existing
ipv4/ipv6 address rows.
The detailed interface view also gains a 'link mode' row carrying the
pmd-type / phy-type-derived label.
Migration of existing startup configurations
--------------------------------------------
Bump confd version 1.8 → 1.9 to trigger the migration on upgrade.
share/migrate/1.9/10-ethernet-advertise.sh translates old configs of
the form
ethernet { auto-negotiation { enable false; } speed S; duplex D; }
into
ethernet { auto-negotiation { advertised-pmd-types [PMD]; } duplex D; }
mapping (S, D) → PMD via a static lookup covering the copper-T speeds
the deprecated speed leaf historically supported (10/100/1000/2.5G/
5G/10G). Interfaces that don't disable auto-negotiation, or that
lack a speed leaf, are passed through untouched.

Add board support for the BananaPi BPI-R4 router board, based on the
MediaTek MT7988A (Filogic 880) SoC with quad-core Cortex-A73 CPU.
The BPI-R4 is the successor to the BPI-R3 but uses entirely different
silicon: the internal switch runs at 2.5 GbE per port, the two SFP+
uplinks use native USXGMII at up to 10 Gbps, and WiFi is provided by
a MediaTek MT7996E PCIe module supporting tri-band WiFi 7 (2.4/5/6 GHz).
Two board variants, BPI-R4-2g5 and BPI-R4P, replace one SFP+ cage with
a 2.5 GbE RJ45 port (using the MT7988A internal 2.5G PHY); the R4P adds
an optional PoE daughterboard on that port. Both use the upstream
mt7988a-bananapi-bpi-r4-2g5 device tree.
Interfaces:
- Standard R4: eth1 (gmac1/sfp2 LAN cage) → sfp2, eth2 (gmac2/sfp1 WAN cage) → sfp1
- R4-2g5/R4P: eth1 (2.5G PHY) → wan, eth2 (gmac2/sfp1 WAN cage) → sfp1
Factory reset / WPS button (GPIO14, active-low): detected by U-Boot at
boot for factory reset; reused by Linux as KEY_WPS_BUTTON at runtime.
eMMC install note: the MT7988A eMMC (pins 38-49) and SD card (pins 32-37)
use separate physical pads so there is no electrical bus sharing, unlike
some BPi-R3 configurations. However, a single MMC controller
(mmc@11230000) handles both, so only one is active per boot session.
The eMMC install procedure therefore still requires an intermediate SPI
NAND bootloader step until a Linux-side install path is tested.
SD card build (bpi_r4_sd_boot_defconfig) now uses the new
mt7988a_bpir4_sd U-Boot defconfig with cap-sd-highspeed enabled,
giving 50 MHz SD transfers instead of the previous 25 MHz legacy mode.
Also adds MT7988/MT7996 firmware support to the buildroot linux-firmware
package, for 2.5 GbE port PHY and WiFi7 extension board, and updates the
aarch64_defconfig, aarch64_minimal_defconfig, the arch README, CI
boot/image workflows, mkimage.sh, and the ChangeLog.
