Add support for static ARP (IPv4) and neighbor cache (IPv6) entries per
interface. Static entries are installed as permanent kernel neighbor
table entries that are never evicted by normal ARP/NDP aging.

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.

Issue #1461 turned out to just be a flaky test, the change in this
commit only bumps the release date.

Add several entries that were missing from the original release notes,
most notably the SBSA watchdog fix for CN913x (Marvell Octeon) platforms
and the BPI-R3 watchdog fix, plus show keystore, ixll scan, show system
temperature, WiFi signal strength inversion fix, and follow command fix.

When a YANG model change breaks existing startup configs, a migration
script must be included or devices in the field may be left unbootable
after upgrade. Add a dedicated section explaining when scripts are
needed, where they live, and how they work.

Infix now advertises _workstation._tcp, making devices appear
automatically in Windows Explorer's Network folder (Win 10 1709+).
Lead with this, show .local hostname usage for ping/SSH, and demote
the IPv6 multicast ping caveat to a note.

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.
