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

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.

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.

and the BPI-R3 watchdog fix, plus show keystore, ixll scan, show system
temperature, WiFi signal strength inversion fix, and follow command fix.

DNS does not allow CNAME records at an apex domain (e.g. kernelkit.org),
so GitHub Pages cannot reliably redirect kernelkit.github.io to it. A
www subdomain can carry a CNAME pointing directly to kernelkit.github.io,
giving GitHub full control over the mapping and making the redirect work.
