ixl(4) will list all of the supported module types for the device if you use ifconfig -m, but I know that isn't the intended purpose of the -m flag. I wouldn't mind moving all of that to another function whose purpose is to just list all supported module types. - Eric On Wed, Jul 15, 2015 at 3:26 PM Alan Somers <asomers@freebsd.org> wrote: > SIOCGIFMEDIA will return the list of supported media types and the > current media type of a network interface.
