In a fit of “why isn’t it doing anything”, I have gone back to Debian Bullseye + linux-image-arm64 from unstable, which at the moment is 5.14.16

`arm-smmu.disable_bypass=0 iommu.passthrough=1` in /etc/default/grub finally had the desired effect.

I was not able to build the ‘master’ branch of restool sources linked above, but then newer ‘integration’ branch did build and install. The kernel option `CONFIG_FSL_MC_UAPI_SUPPORT=y` is the relevant one.

> ls-listmac  
> dprc.1/dpmac.17 (end point: dpni.0)  
> dprc.1/dpmac.10  
> dprc.1/dpmac.9  
> dprc.1/dpmac.8  
> dprc.1/dpmac.7  
> dprc.1/dpmac.6  
> dprc.1/dpmac.5  
> dprc.1/dpmac.4  
> dprc.1/dpmac.3

Update /etc/network/interfaces with a few options, not limited to dhcp

> ls-addni dpmac.9

restart networking, top left works, and continuing…

[dpmac.9][dpmac.7]  
[dpmac.10][dpmac.8] [?] [serial console usb] [eth0] [usb3] [sd]

ethX is assigned in order of commands.

Final note, when making a systemd ls-addni.service - to run before networking starts, apparently you should use

> Before=network-pre.target  
> Wants=network-pre.target

Thank you.
