NSA325v2 no network (eth0 missing) (2 replies)

I've sucessfully managed to boot kernel 5.1.11 with Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi, thanks Bodhi!
Uboot is U-Boot 2017.07-tld-1, I'm using USB drive with ext4 filesystem. Uboot is simple for me:

setenv bootargs_linux 'console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=nand_mtd:0x100000(uboot),0x80000(uboot_env),0x80000(key_store),0x80000(info),0xA00000(etc),0xA00000(kernel_1),0x2FC0000(rootfs1),0xA00000(kernel_2),0x2FC0000(rootfs2) earlyprintk=serial'
setenv bootcmd_linux 'setenv bootargs $bootargs_linux; mw.l f1010100 0020c000; usb reset; ext4load usb 0:1 0x800000 /boot/uImage; ext4load usb 0:1 0x02100000 /boot/uInitrd; ext4load usb 0:1 0x1c00000 /boot/dts/kirkwood-dns325.dtb; bootm 0x800000 0x02100000 0x1c00000'

But there is some problem (maybe with DTB?) with ethernet, I can see kernel message:

[    8.450525] mdio_bus f1072004.mdio-bus-mii: MDIO device at address 8 is missing.
[    8.458797] mv643xx_eth: MV-643xx 10/100/1000 ethernet driver version 1.4
[    8.466686] mv643xx_eth_port mv643xx_eth_port.0: DMA mask not set

And eth0 is completely missing...
