Hello!
I have been searching on Internet for implementation of UDLR protocol =
(RFC 3077).
AFAI see this protocol support is implemented only for Cisco platform.
I am thinking of implementing some kind of virtual network device which =
uses TX
of one NIC and RX of another NIC. As a result I will get a device with =
similar to
RFC 3077 functionality.
I am a little new to low level kernel development so the question is: =
what would
be the staff to start with?

Thanks for help!
