New Revision: 281796
URL: https://svnweb.freebsd.org/changeset/base/281796
Log:
Don't blindly assume that the softc returned is going to match up to the
em(4) notion of what an adapter struct is. Check to see if the device
matches *first* and *then* assume that we can use it as an adapter
structure for parsing.
