it's kind of unfortunate that in dhcpd.leases it was called 'uid', but
what it means is 'dhcp-client-identifier'.
i gather from comments there was some hope that people would soon be
calling these "globally unique identifiers," but it's clear this has
not panned out.

the vendor-class-identifier is not the dhcp-client-identifier. you'd
have to show us the vendor-class-identifier this device is emitting if
you wanted to match clients this way.
