 That appears to be progress, anyway...

 Certainly. Where's it entering ddb? The error return chain seems to be
 correct up through wpi_init returning failure, none of the direct
 calls from inside if_wpi check that return at all (which is perhaps
 broken but not likely to land in ddb) and above that it's some
 indirect call through ->if_init from the network stack, and there are
 quite a few possible choices.
