NAME

     kse -- Micrel 8842/8841 PCI Ethernet controller driver

SYNOPSIS

     kse* at pci? dev ? function ?

DESCRIPTION

     The kse driver supports Ethernet interfaces based on the Micrel 8842/8841 PCI Ethernet chips.  The 8842 has 2 Ethernet ports which behave as
     a managed switch to bridge each other.  It works like a T-shape connector of Ethernet data flow in which an Ethernet controller sits at the
     leg of the T.  Frames can flow between the two ports while traffic destined for the 8842 reaches the EMAC.  The 8841 is a plain 10/100 Ether-
     net.  The kse driver distinguishes and handles them according to the HW model.

AUTHORS

     The kse driver was written by Tohru Nishimura.

BUGS

     __STRICT_ALIGNMENT case is not written.  8842 media selection keeps ``auto'' and indicates ``up 100baseTX-FX flow'' when either of two ports
     is found link-up.	There is no functional provision to see and control the media selection of them this moment.  Advanced features like flow
     volume bound, VLAN tag insertion/removal, QoS DiffServ are not implemented and remain uncontrollable by the kse driver.  UDP4CSUM is not very
     useful since the HW has an implementation error for the case when a large UDP datagram is fragmented into MTU sized frames.

NAME

     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.

HISTORY

     The gsip driver first appeared in NetBSD 1.6.

AUTHORS

     The gsip driver was written by Jason R. Thorpe <thorpej@NetBSD.org>.

BUGS

     The gsip driver does not support the 10-bit interface, which is required in order to support fiber-optic media.
