Constant pcap::linktypes::PPP

pub const PPP: i32 = 9;

DLT_PPP PPP, as per RFC 1661 and RFC 1662; if the first 2 bytes are 0xff and 0x03, it's PPP in HDLC-like framing, with the PPP header following those two bytes, otherwise it's PPP without framing, and the packet begins with the PPP header. The data in the frame is not octet-stuffed or bit-stuffed.
