Many thanks Remy for having filled out the SRU template, the updated
debdiff and the details.

LGTM now

I've uploaded the updated package now ...

** Description changed:

+ SRU Justification:

  [ Impact ]
  * eth0 is not a predictable_names. The Jetson AGX Orin board uses the on-chip ethernet MAC plus an on-board Ethernet PHY. Since it is not a PCIe device, it does not get discovered and named. Considering the case, its name should anyway be defined to eno1.
  * This upload should statically define it for this platform and this driver in particular. Note that since only jammy images currently exist on this platform, systemd comes with v249, which prevent us from using the DT alias names feature introduced with v252.

  [ Where problems could occur ]
  * nvidia-tegra-default applies default extra configuration for system based on Nvidia Tegra ORIN SoC. Installing it on other ARM64 systems could lead to unexpected behavior. However, as this is an extra package not listed in any image definitions (except the Tegra ones), no problem is expected to occur for current Ubuntu users.
  
  [ Other Info ]

  [ Other Info ]
  * Since device tree alias support got introduced in systemd/networkd v252
    (and newer), noble and oracular are not affected by this,
    and the SRU is for jammy only.
  * This is related to LP #2071428 (Riverside)
