Build breakage in the "en" module

With this morning's sources, my kernel build is failing in the "en"
module:

*** Error code 1

At line 1474, the incomplete type is "struct atmio_vcctable".  I
grepped all of the *.h files under src/sys, but none of them
contained "atmio_vcctable".  Perhaps a new header file was omitted
from the commit?
