Are layer 2 protocols like IEEE 802.2 (LLC), PPP, HDLC, frame relay, etc part of NIC or NIC's device driver at kernel?When we configure layer 2 protocol to be used like PPP, where is the configuration file stored?The only thing I am quite sure is IEEE 802.3 has to be part of NIC because it controls the transceiver (transmit/receive) activity on the medium/media.
