Just wondering if you think something like the patch below is
suitable/acceptable for insulating netconsole from inconsistent device
name scenarios without changing the existing semantics. The basic idea
is to allow an ethernet MAC address in the <dev> field of the
netconsole= options, and if a MAC address was specified rather than a
device name, to do the dev lookup from the MAC address instead.

This doesn't extend to, but also doesn't interfere with, the dynamic
config of netconsole via configfs.

Would you mind reviewing it?

This is a good idea. Just that you need to complete the configfs
interface too.
