esh -- RoadRunner-based HIPPI interfaces device driver SYNOPSIS
esh* at pci? dev ? function ? DESCRIPTION
The esh device driver supports the Essential Communications RoadRunner-based HIPPI interfaces. With some modifications, the driver could be made to support the Gigabit Ethernet card based on the same chip. 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 /dev/eshN/ulpN set of devices. There are 255 available Upper Layer Protocols in FP; these are selectable via the various device entries. 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 the default socket buffer size should be increased to at least 192KB, regardless of the expected bandwidth-delay product of the network. HIPPI ARP is not widely used, and the NetBSD stack does not support it (yet). In order to define the mappings between IP addresses and ifields (the HIPPI MAC addresses), the administrator must make link-layer entries in the routing table using the route(8) command: route add -interface -llinfo -link esh0: MEDIA SELECTION
Media selection is not yet supported for this device. SEE ALSO
intro(4), pci(4), eshconfig(8), ifconfig(8), route(8) BUGS
The card must be tuned for proper and efficient DMA operation. The appropriate values vary based on the system. The eshconfig(8) program is used for this. BSD

gsip -- National Semiconductor DP83820 Gigabit Ethernet driver SYNOPSIS
gsip* at pci? dev ? function ? Configuration of PHYs may also be necessary. See mii(4). DESCRIPTION
The gsip device driver supports Gigabit Ethernet interfaces based on the National Semiconductor DP83820 Gigabit Ethernet chips. The National Semiconductor DP83820 is found on NetGear GA-622, Asante FriendlyNet GigaNIX, D-Link DGE-500T, SMC 9452TX and 9462TX, Accton EN1407-T, Planex GN-1000TE, ARK SOHO GA2000T and GA2500T, and other low-cost Gigabit Ethernet cards. It uses an external PHY or an external 10-bit interface. The DP83820 supports VLAN tag insertion/removal in hardware. The gsip driver supports this feature of the chip. The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The gsip driver supports this feature of the chip. See ifconfig(8) for informa- tion on how to enable this feature. The DP83820 chip is a close relative of the DP83815 10/100 Ethernet chip, which is supported by the sip(4) driver, hence the gsip name. SEE ALSO
arp(4), ifmedia(4), mii(4), netintro(4), pci(4), vlan(4), ifconfig(8) HISTORY
The gsip driver first appeared in NetBSD 1.6. AUTHORS
The gsip driver was written by Jason R. Thorpe <>. BUGS
The gsip driver does not support the 10-bit interface, which is required in order to support fiber-optic media. BSD
