There is nothing to fix here or to backport to stable. The defconfigs are just examples, useful for development and for downstream. If you really think there is a bug which should be fixed, then there should be dependency on JZ4780_EFUSE by Ethernet driver.

The commit 19c968222934 ("MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the default MAC address") add EFUSE node for DM9000 in CI20, however, the EFUSE driver is not selected, which will cause the DM9000 to fail to read the MAC address from EFUSE, causing the following issue: [FAILED] Failed to start Raise network interfaces. Fix this problem by select CONFIG_JZ4780_EFUSE by default in the ci20_defconfig. Fixes: 19c968222934 ("MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the default MAC address").
