Per my OP, see this dmesg output (this from Armbian which was running with full networking at time of ethernet loss. I haven't done so much troubleshooting with other bootable OS images, instead just checked for presence of any network with ifconfig and/or nmtui.):
Code:
dwmac-sun8i 1c30000.ethernet: IRQ eth_wake_irq not found
dwmac-sun8i 1c30000.ethernet: IRQ eth_lpi not found
dwmac-sun8i 1c30000.ethernet: PTP uses main clock
dwmac-sun8i 1c30000.ethernet: 1c30000.ethernet supply phy-io not found, using dummy regulator
dwmac-sun8i 1c30000.ethernet: Current syscon value is not the default 2001 (expect 0)
dwmac-sun8i 1c30000.ethernet: No HW DMA feature register supported
dwmac-sun8i 1c30000.ethernet: RX Checksum Offload Engine supported
dwmac-sun8i 1c30000.ethernet: COE Type 2

dwmac-sun8i 1c30000.ethernet: Normal descriptors

dwmac-sun8i 1c30000.ethernet: EMAC reset timeout
dwmac-sun8i 1c30000.ethernet eth0: stmmac_dvr_remove: removing driver
dwmac-sun8i: probe of 1c30000.ethernet failed with error -14
The kernel / uboot cannot detect the presence of an ethernet hardware device.
[edit] USB wifi dongles are detected and configured without issue.
