HIPPI interfaces. With some modifications, the driver could be
made to support the Gigabit Ethernet card based on the same chip.
.Pp
The driver supports both a normal network interface and a raw
HIPPI Framing Protocol (HIPPI-FP) device.
The HIPPI-FP interface is accessed via the
.Pa /dev/esh Ns Sy N/ulp Ns Sy N
set of devices. There are 255 available Upper Layer Protocols
in FP; these are selectable via the various device entries.
.Pp
HIPPI is an 800-megabit/sec networking technology which supports
extremely large packet sizes. In order to efficiently use this
network, the kernel should be configured with extra mbufs, and
