Hi!

[ Upstream commit 31d929de5a112ee1b977a89c57de74710894bbbf ]
When the name_assign_type attribute was introduced (commit 685343fc3ba6, "net: add name_assign_type netdev attribute"), the loopback device was explicitly mentioned as one which would make use of NET_NAME_PREDICTABLE:
The name_assign_type attribute gives hints where the interface name of a given net-device comes from. These values are currently defined:
... NET_NAME_PREDICTABLE: The ifname has been assigned by the kernel in a predictable way that is guaranteed to avoid reuse and always be the same for a given device. Examples include statically created devices like the loopback device [...]
Switch to that so that reading /sys/class/net/lo/name_assign_type produces something sensible instead of returning -EINVAL.
This was already part of the previous autosel:
