  Solaris (2.6, at least) uses DLPI but it doesn't have a dlpi device.
Instead, you must open the interface driver directly.  E.g. to listen on
hme0, you would have to modify the permissions on /dev/hme.  I verified
this with a quick experiment on a Solaris box here, and after enabling
read-write permissions on the device, I could capture just fine as a
normal user.  Read-only permissions didn't work.
