Crap. Did build-test, but only x86_64, so I missed this apparently
mips-specific breakage. Locally fixed up, but waiting to see if anyone has
any other feedback about these two patches before I go ahead with v2. Also
have a ~15-part drivers/net/ethernet/ cleanup series ready and waiting,
pending some traction with the core infra.
