Asymetric download on WAN & Ethernet only RPI5

[HarukuCode]

Describe the bug

Severe asymmetric throughput degradation on Raspberry Pi 5 onboard Ethernet (RP1, macb driver) specifically on WAN traffic, correlated with a steady increase in rx_overruns. LAN traffic (Ethernet or WiFi) is unaffected. WiFi WAN is unaffected. Only Ethernet WAN download is broken.

Steps to reproduce the behaviour

1. Boot Raspberry Pi 5 with default Raspberry Pi OS, connected via onboard Ethernet to a router with WAN internet access (ISP: Free SAS, fiber, symmetric gigabit line).
2. Run speedtest (Ookla CLI) repeatedly.
3. Observe download throughput capped around 3-5 Mbps while upload reaches 500-850 Mbps.
4. Monitor ethtool -S eth0 | grep overrun before/after — rx_overruns increases continuously during download-heavy WAN traffic, does not increase under LAN-only traffic.
5. Compare against WiFi on the same router: both directions perform normally

Additional context

Diagnosis / troubleshooting performed

• Ring buffer: increased RX ring from 512 to max (8192) via ethtool -G eth0 rx 8192 tx 4096 — no improvement, overruns still increase linearly with WAN download traffic (~1000-2000 per ~15s test).
• EEE: not supported by this driver (ethtool --set-eee returns netlink error: Operation not supported).
• Forced link speed: tested at 100Mb/Full (ethtool -s eth0 speed 100 duplex full autoneg off) — overruns still present, and upload throughput also collapsed to ~8 Mbps at this speed, ruling out a gigabit-specific issue.
• CPU load: mpstat -P ALL 1 10 during WAN download shows all 4 cores essentially idle (>99% idle) — rules out CPU/IRQ starvation from general system load.
• Firmware/kernel update: apt full-upgrade + rpi-eeprom-update -a + reboot — overruns reset to 0 after reboot but reappear immediately under WAN download load (1023 overruns after a single speedtest).
• Physical layer: ethtool -S eth0 shows zero rx_frame_check_sequence_errors, rx_alignment_errors, rx_symbol_errors — cable/signal integrity ruled out.
• Flow control: link reports flow control off (macb 1f00100000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off in dmesg).

Maybe hardware related ? I did not use it in 2 years because of this, Amazon won't take it back it's too late. I should not have spent my time on this lol

Update: tested with kernel 6.1.77 (rpi-firmware commit 5fc4f643d2e9c5aa972828705a902d184527ae3f) via rpi-update, one of the earliest kernels supporting Pi 5 hardware. The bug is still present with identical symptoms (rx_overruns climbing, download capped ~4Mbps on WAN). This rules out a recent kernel regression — the issue appears to have been present since RP1 ethernet support was first introduced.
