IRIXFDDI (Raw FDDI Driver (IRIX platform))
IRIXFDDI is a user-space x-kernel FDDI driver that sends and receives messages using IRIX raw sockets.
IRIXFDDI places and receives packets directly on the wire using the SGI raw socket interface. Using raw sockets is a priviledged operation, so the user must be root or the running xkernel must be owned by root and have the suid bit set.
IRIXFDDI is in the ANCHOR realm, supporting the FDDI driver interface described in FDDI.
IRIXFDDI supports the fddi driver interface rather than a standard xkernel UPI interface and thus makes no use of participant stacks.
IRIXFDDI adheres to the external interface defined by FDDI.
IRIXFDDI requires no lower protocol. It can be configured in either the driver section or the protocol section of graph.comp.
IRIXFDDI recognizes the following ROM options:
irixfddi mmmm nnnn: This instantiation of irixfddi should use IRIX raw socket send port mmmm and receive port nnnn. There must be such a line for each instantiation of IRIXFDDI in the x-kernel .
