Nor does it prevent libpcap (once I generalize the remote-capture = mechanism) from supporting gsmtap://{host}[:port] (port optional) URLs = that cause it to set up a UDP ({PF_INET or PF_INET6}, SOCK_DGRAM, = IPPROTO_UDP) socket on which to receive UDP packets from the specified = host (at the specified port or, if no port is specified, the default = GSMTAP socket) and supplying packets that begin with a GSMTAP header, = with a new linktype of LINKTYPE_GSMTAP/DLT_GSMTAP.=
