o Bump version number to 3.0.4 o When talking to a RADIUS server, provide a NAS-Port-Type. When the NAS-Port-Type is Ethernet, provide a NAS-Port value equal to the SESSIONID from the environment in direct mode or the NGM_PPPOE_SESSIONID message in other modes. If no SESSIONID is found, default to the interface index in client mode or zero in server mode. When the NAS-Port-Type is ISDN, set the NAS-Port to the minor number of the physical device (ie, the N in /dev/i4brbchN). This makes it easier for the RADIUS server to identify the client WRT accounting data etc. Prompted by: lsz8425 <lsz8425@mail.cd.hn.cn>
