Here's what I had in mind when I replied to phk. This seems to work well. The included message doesn't have the conf/mii.all file, but that looks like # # All the PHy devices. If your NIC has a subset of these, you can refrain # from adding the include line in your config file and instead list # the individual devices you need for your setup. # # $FreeBSD$ # device acphy device amphy device bmtphy device brgphy device ciphy device dcphy device e1000phy device exphy device inphy device lxtphy device mlphy device nsgphy device nsphy device pnaphy device pnphy device qsphy device rgephy device rlphy device ruephy device tdkphy device tlphy device xmphy device miibus If we start moving the PHYs used by only one driver to their modules, this might save a small amount in the miibus.ko. However, those drivers will still need the entire miibus.ko file anyway. I'd rather we not premature submicro optimize the module builds for a while to give me a chance to succeed or fail on the module work I'm about to start on.

Future work on the module system to parse files* will # correct this shortcoming.
