It first use "open" system call to open something like /dev/bge, then send strbuf containing DL_ATTACH_REQ to the opened STREAMS. It uses dlpi device to get the mac address. > > If it doesn't use libdlpi, does it have support for Solaris "vanity > naming," which requires looking in /dev/net/ for the device first? It doesn't looking in /dev/net/, but it seems works ok on renamed link, e.g. the command "iftop -i e1kg1" shows the traffic on e1kg1 where e1kg1 is the renamed name of e1000g1. For capture packets, it uses pcap_open_live to open the interface. It seems libpcap support vanity naming. > > If it doesn't do that, could a fix be contributed back upstream?
