DL_BIND_REQ

I believe the SAP is equivalent to the DLT type for DLPI.

Looking in pcap-dlpi.c, libpcap uses '0' as the SAP - I imagine
this works as a wildcard - when it calls dlbindreq().

Or maybe I'm confused about the role of SAP and DLT here.

I do know that if you want IPv4 only frames or IPv6 only frames
in Solaris8 and beyond, setting the SAP to 0x800 or 0x86dd should
solve that problem for you (0x800 == ETHERTYPE_IP.)
